is included by sched.h and module.h and thus ends up being\nincluded when building most .c files. percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed. 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": "441f4058a04b2943685ff94e0f5f1992b0b3649e", "tree": "80a61f6dddcf7d5831a8bd3771ffa2b430af3935", "parents": [ "7c34691abe23741bfc7d2514efd5a39f0e0ecb06", "8ad6fcab564c5bc956bdc3dfa440ab152b6e780f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 18 16:50:55 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 18 16:50:55 2010 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable: (30 commits)\n Btrfs: fix the inode ref searches done by btrfs_search_path_in_tree\n Btrfs: allow treeid\u003d\u003d0 in the inode lookup ioctl\n Btrfs: return keys for large items to the search ioctl\n Btrfs: fix key checks and advance in the search ioctl\n Btrfs: buffer results in the space_info ioctl\n Btrfs: use __u64 types in ioctl.h\n Btrfs: fix search_ioctl key advance\n Btrfs: fix gfp flags masking in the compression code\n Btrfs: don\u0027t look at bio flags after submit_bio\n btrfs: using btrfs_stack_device_id() get devid\n btrfs: use memparse\n Btrfs: add a \"df\" ioctl for btrfs\n Btrfs: cache the extent state everywhere we possibly can V2\n Btrfs: cache ordered extent when completing io\n Btrfs: cache extent state in find_delalloc_range\n Btrfs: change the ordered tree to use a spinlock instead of a mutex\n Btrfs: finish read pages in the order they are submitted\n btrfs: fix btrfs_mkdir goto for no free objectids\n Btrfs: flush data on snapshot creation\n Btrfs: make df be a little bit more understandable\n ...\n" }, { "commit": "8ad6fcab564c5bc956bdc3dfa440ab152b6e780f", "tree": "38670d63e5315650f3e6efe2a2a8025e945b4743", "parents": [ "1b53ac4d1b75b23bdc2b54ace787b8f718a987ef" ], "author": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Thu Mar 18 12:23:10 2010 -0400" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Thu Mar 18 12:23:10 2010 -0400" }, "message": "Btrfs: fix the inode ref searches done by btrfs_search_path_in_tree\n\nThis is used by the inode lookup ioctl to follow all the backrefs up\nto the subvol root.

We cannot currently\nmount a subvolume of a subvolume, you can only mount subvolumes/snapshots of the\ndefault subvolume. So say you take a snapshot of the default subvolume and call\nit snap1, and then take a snapshot of snap1 and call it snap2, so now you have\n\n/\n/snap1\n/snap1/snap2\n\nas your available volumes. Currently you can only mount / and /snap1,\nyou cannot mount /snap1/snap2. To fix this problem instead of passing\nsubvolid\u003d\u003cname\u003e you must pass in subvolid\u003d\u003ctreeid\u003e, where \u003ctreeid\u003e is\nthe tree id that gets spit out via the subvolume listing you get from\nthe subvolume listing patches (btrfs filesystem list). This allows us\nto mount /, /snap1 and /snap1/snap2 as the root volume.\n\nIn addition to the above, we also now read the default dir item in the\ntree root to get the root key that it points to. For now this just\npoints at what has always been the default subvolme, but later on I plan\nto change it to point at whatever root you want to be the new default\nroot, so you can just set the default mount and not have to mount with\n-o subvolid\u003d\u003ctreeid\u003e.
