We still use the BKL as long as fs/lockd\nuses it and ceph might sleep, but we can flip the definition\nto a private spinlock as soon as that\u0027s done.\nAll users outside of fs/lockd get converted to use\nlock_flocks() instead of lock_kernel() where appropriate.\n\nBased on an earlier patch to use a spinlock from Matthew\nWilcox, who has attempted this a few times before, the\nearliest patch from over 10 years ago turned it into\na semaphore, which ended up being slower than the BKL\nand was subsequently reverted.\n\nSomeone should do some serious performance testing when\nthis becomes a spinlock, since this has caused problems\nbefore. Using a spinlock should be at least as good\nas the BKL in theory, but who knows...\n\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: Matthew Wilcox \u003cwilly@linux.intel.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: \"J.

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": "2597641deae82c9a95e255518da189ab557da0af", "tree": "0b2dc7c46f2a0398ecefd6bb63a657710cf921fa", "parents": [ "0629e370dd5819efa5cf8d418a8e6729efe388ef" ], "author": { "name": "Alexandros Batsakis", "email": "batsakis@netapp.com", "time": "Sat Dec 05 13:48:55 2009 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Dec 05 13:48:55 2009 -0500" }, "message": "nfs41: v2 fix cb_recall bug\n\nin NFSv4.1 the seqid part of a stateid in CB_RECALL must be 0\n\nSigned-off-by: Alexandros Batsakis \u003cbatsakis@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "31f0960778c78198957cf02cc970d92b72b929e4", "tree": "b5d061437c4a952e0fe78006a2ad9186c2e6ecc9", "parents": [ "c79571a508801e055a0be583d6dc70bddad7bb64" ], "author": { "name": "Alexandros Batsakis", "email": "batsakis@netapp.com", "time": "Sat Dec 05 13:27:02 2009 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Dec 05 13:27:02 2009 -0500" }, "message": "nfs41: V2 initial support for CB_RECALL_ANY\n\nFor now the clients returns _all_ the delegations of the specificed type\nit holds\n\nSigned-off-by: Alexandros Batsakis \u003cbatsakis@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "c79571a508801e055a0be583d6dc70bddad7bb64", "tree": "a5000c191610376a01f12ac54c08d3c1adcf5bea", "parents": [ "b4a6f4966efc7e70dc8d8a9e60744de6845b14bf" ], "author": { "name": "Alexandros Batsakis", "email": "batsakis@netapp.com", "time": "Sat Dec 05 13:20:52 2009 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Dec 05 13:20:52 2009 -0500" }, "message": "nfs4: V2 return/expire delegations depending on their type\n\nSigned-off-by: Alexandros Batsakis \u003cbatsakis@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "b4a6f4966efc7e70dc8d8a9e60744de6845b14bf", "tree": "72a2b2687975bc3629dd02efca6bc879fa2bcbfe", "parents": [ "07bccc2dd4e8745859f0fa7d120ea39320fbcdbf" ], "author": { "name": "Alexandros Batsakis", "email": "batsakis@netapp.com", "time": "Sat Dec 05 13:19:11 2009 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Dec 05 13:19:11 2009 -0500" }, "message": "nfs4: minor delegation cleaning\n\nSigned-off-by: Alexandros Batsakis \u003cbatsakis@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "d18cc1fda25295416a2855d44c2936db01df9eec", "tree": "962ec82ffff2fb49691779039c76976be7d964f0", "parents": [ "d327cf7449e6fd5cbac784c641770e9366faa386" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Thu Dec 03 08:10:17 2009 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Thu Dec 03 08:10:17 2009 -0500" }, "message": "NFSv4: Fix a potential state manager deadlock when returning delegations\n\nThe nfsv4 state manager could potentially deadlock inside\n__nfs_inode_return_delegation() if the server reboots, so that the calls to\nnfs_msync_inode() end up waiting on state recovery to complete.\n\nAlso ensure that if a server reboot or network partition causes us to have\nto stop returning delegations, that NFS4CLNT_DELEGRETURN is set so that\nthe state manager can resume any outstanding delegation returns after it\nhas dealt with the state recovery situation.\n\nFinally, ensure that the state manager doesn\u0027t wait for the DELEGRETURN\ncall to complete.

a full sockaddr_in to include the port\n number (will be required for NFS2/3).\n\n (5) Make nfs_find/get_client() take the NFS protocol version (again will be\n required to differentiate NFS2, 3 \u0026 4 client records).\n\nAlso:\n\n (6) Make nfs_client construction proceed akin to inodes, marking them as under\n construction and providing a function to indicate completion.\n\n (7) Make nfs_get_client() wait interruptibly if it finds a client that it can\n share, but that client is currently being constructed.\n\n (8) Make nfs4_create_client() use (6) and (7) instead of locking
