Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "009d851837ab26cab18adda6169a813f70b0b21b", "tree": "073bc05e3a8c527bf9ce3332e2c2f6694484984d", "parents": [ "30ff056c42c665b9ea535d8515890857ae382540" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Tue Dec 08 12:12:13 2009 +0000" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Mar 01 14:07:37 2010 +0000" }, "message": "GFS2: Metadata address space clean up\n\nSince the start of GFS2, an \"extra\" inode has been used to store\nthe metadata belonging to each inode. The only reason for using\nthis inode was to have an extra address space, the other fields\nwere unused. This means that the memory usage was rather inefficient.\n\nThe reason for keeping each inode\u0027s metadata in a separate address\nspace is that when glocks are requested on remote nodes, we need to\nbe able to efficiently locate the data and metadata which relating\nto that glock (inode) in order to sync or sync and invalidate it\n(depending on the remotely requested lock mode).\n\nThis patch adds a new type of glock, which has in addition to\nits normal fields, has an address space. This applies to all\ninode and rgrp glocks (but to no other glock types which remain\nas before). As a result, we no longer need to have the second\ninode.\n\nThis results in three major improvements:\n 1. A saving of approx 25% of memory used in caching inodes\n 2. A removal of the circular dependency between inodes and glocks\n 3. No confusion between \"normal\" and \"metadata\" inodes in super.c\n\nAlthough the first of these is the more immediately apparent, the\nsecond is just as important as it now enables a number of clean\nups at umount time.

It removes all limits (other than memory\nfor inodes, as per every other filesystem) on numbers of these\nwhich we can support on GFS2. It also means that (like other\nfs) its the responsibility of the last process to close the file\nto deallocate the storage, rather than the person who did the\nunlinking. Note that with GFS2, those two events might take place\non different nodes.\n\nAlso there are a number of other changes:\n\n o We use the Linux inode subsystem as it was intended to be\nused, wrt allocating GFS2 inodes\n o The Linux inode cache is now the point which we use for\nlocal enforcement of only holding one copy of the inode in\ncore at once (previous to this we used the glock layer).\n o We no longer use the unlinked \"special\" file. We just ignore it\ncompletely. This makes unlinking more efficient.\n o We now use the 4th block allocation state. The previously unused\nstate is used to track unlinked but still open inodes.\n o gfs2_inoded is no longer needed\n o Several fields are now no longer needed (and removed) from the in\ncore struct gfs2_inode\n o Several fields are no longer needed (and removed) from the in core\nsuperblock\n\nThere are a number of future possible optimisations and clean ups\nwhich have been made possible by this patch.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "382066da251132f768380f4852ed5afb72d88f80", "tree": "f8ae69e6b441452f9958f45cea15a0cf90baa39d", "parents": [ "9229f013495dcdae76e9942ebc2cfc69851fe10a" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Wed May 24 10:22:09 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Wed May 24 10:22:09 2006 -0400" }, "message": "[GFS2] Casts for printing 64bit numbers\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "3a8a9a1034813aa99f5ae3150f652d490c5ff10d", "tree": "427d4c1499b5c88dbf43c6e490d83cee350083b2", "parents": [ "bd8968010a9a08e67a0ddb3ddee9feb8882e8c2f" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 15:09:15 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 15:09:15 2006 -0400" }, "message": "[GFS2] Update copyright date to 2006\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "bd8968010a9a08e67a0ddb3ddee9feb8882e8c2f", "tree": "c3960853310112779e2ce583a8c8b524777cb70d", "parents": [ "1b50259bc33f2adfcb4c5fba4b740bf80789df22" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 14:54:58 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 18 14:54:58 2006 -0400" }, "message": "[GFS2] Remove semaphore.h from C files\n\nWe no longer use semaphores, everything has been converted to\nmutex or rwsem, so we don\u0027t need to include this header any more.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "1e09ae544eb1a2d11b04c6924f738a310c7a7a2b", "tree": "d5be98602097f1e3b050f6f2b32ac0ecac53cea2", "parents": [ "1dde2dbfc70001e2f86b6581baac2f48900b80ed" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri Apr 21 15:52:46 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri Apr 21 15:52:46 2006 -0400" }, "message": "[GFS2] Move BUG() back into the header file\n\nIn order to make the file and line number reporting work\ncorrectly, this has been moved back into the header file.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "1dde2dbfc70001e2f86b6581baac2f48900b80ed", "tree": "361a5838d93a5674578f3626cf55a932b6da5372", "parents": [ "a74604bee27da7c9506114e5710f91f388e98296" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri Apr 21 15:39:02 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri Apr 21 15:39:02 2006 -0400" }, "message": "[GFS2] Add back missing BUG()\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "71b86f562b5eb6f94ea00bba060caa64d0137969", "tree": "63d982e09a9cb934fe656afe115031c0a9dc5e4a", "parents": [ "94aabbd99370f738da4f6cb4ea0b94cd9024002f" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Tue Mar 28 14:14:04 2006 -0500" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Tue Mar 28 14:14:04 2006 -0500" }, "message": "[GFS2] Further updates to dir and logging code\n\nThis reduces the size of the directory code by about 3k and gets\nreaddir() to use the functions which were introduced in the previous\ndirectory code update.\n\nTwo memory allocations are merged into one.

Fixes for the various bugs will be\nforthcoming shortly.\n\nThis patch removes the special data format which has been used\nup till now for journaled data files. Directories still retain the\nold format so that they will remain on disk compatible with earlier\nreleases. As a result you can now do the following with journaled\ndata files:\n\n 1) mmap them\n 2) export them over NFS\n 3) convert to/from normal files whenever you want to (the zero length\n restriction is gone)\n\nIn addition the level at which GFS\u0027 locking is done has changed for all\nfiles (since they all now use the page cache) such that the locking is\ndone at the page cache level rather than the level of the fs operations.\nThis should mean that things like loopback mounts and other things which\ntouch the page cache directly should now work.\n\nCurrent known issues:\n\n 1. There is a lock mode inversion problem related to the resource\n group hold function which needs to be resolved.\n 2. Any significant amount of I/O causes an oops with an offset of hex 320\n (NULL pointer dereference) which appears to be related to a journaled data\n buffer appearing on a list where it shouldn\u0027t be.\n 3. Direct I/O writes are disabled for the time being (will reappear later)\n 4. There is probably a deadlock between the page lock and GFS\u0027 locks under\n certain combinations of mmap and fs operation I/O.\n 5. Issue relating to ref counting on internally used inodes causes a hang\n on umount (discovered before this patch, and not fixed by it)\n 6. One part of the directory metadata is different from GFS1 and will need\n to be resolved before next release.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "666a2c534cc6238932296a95c9e9c06ca3b73d97", "tree": "c446ee47e6949f8315616b257bd82f918f3792db", "parents": [ "c73530a1f9633b2e7e6e19d0274b575febf8e8dc" ], "author": { "name": "Steven Whitehouse", "email": "steve@chygwyn.com", "time": "Wed Jan 18 10:29:04 2006 +0000" }, "committer": { "name": "Steven Whitehouse", "email": "steve@chygwyn.com", "time": "Wed Jan 18 10:29:04 2006 +0000" }, "message": "[GFS2] Remove unused code from various files\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "b3b94faa5fe5968827ba0640ee9fba4b3e7f736e", "tree": "70bd6068b050d2c46e338484f8b03fae4365c6c3", "parents": [ "f7825dcf8c7301cfd3724eb40c5b443cc85ab7b8" ], "author": { "name": "David Teigland", "email": "teigland@redhat.com", "time": "Mon Jan 16 16:50:04 2006 +0000" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Jan 16 16:50:04 2006 +0000" }, "message": "[GFS2] The core of GFS2\n\nThis patch contains all the core files for GFS2.\n\nSigned-off-by: David Teigland \u003cteigland@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" } ] }
