This governs auto-release of the structure upon execution.\n\nOrdinarily, the work queue executor would release the work_struct for further\nscheduling or deallocation by clearing the pending bit prior to jumping to the\nwork function. This means that, unless the driver makes some guarantee itself\nthat the work_struct won\u0027t go away, the work function may not access anything\nelse in the work_struct or its container lest they be deallocated.. This is a\nproblem if the auxiliary data is taken away (as done by the last patch).\n\nHowever, if the pending bit is *not* cleared before jumping to the work\nfunction, then the work function *may* access the work_struct and its container\nwith no problems. But then the work function must itself release the\nwork_struct by calling work_release().\n\nIn most cases, automatic release is fine, so this is the default. Special\ninitiators exist for the non-auto-release case (ending in _NAR).\n\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "bf02c082bf7a464518d45b9c178b8aa83f74dd5d", "tree": "8c0aafa48ec5e2298d76d58baf67bd59a5fa95ae", "parents": [ "49a6cbe1cd8a72451d9d6ab5b1e163f17c1bbee3" ], "author": { "name": "Andreas Mohr", "email": "andi@rhlx01.fht-esslingen.de", "time": "Wed Oct 11 01:22:24 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 11 11:14:25 2006 -0700" }, "message": "[PATCH] fs/bio.c: tweaks\n\n- Calculate a variable in bvec_alloc_bs() only once needed, not earlier\n (bio.o down from 18408 to 18376 Bytes, 32 Bytes saved, probably due to\n data locality improvements).\n\n- Init variable idx to silence a gcc warning which already existed in the\n unmodified original base file (bvec_alloc_bs() handles idx correctly, so\n there\u0027s no need for the warning):\n\n\tfs/bio.c: In function `bio_alloc_bioset\u0027:\n\tfs/bio.c:169: warning: `idx\u0027 may be used uninitialized in this function\n\nSigned-off-by: Andreas Mohr \u003candi@lisas.de\u003e\nAcked-by: Jens Axboe \u003caxboe@kernel.dk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0fe23479577124bd2687e6783e39fa0fa4c28005", "tree": "954ae8c079fd10cd52bf212ca5cd2530ec5c2315", "parents": [ "50be345560f1ffdcb15cc0e146416b80529a2ef2" ], "author": { "name": "Jens Axboe", "email": "axboe@kernel.dk", "time": "Mon Sep 04 15:41:16 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:52:34 2006 +0200" }, "message": "[PATCH] Update axboe@suse.de email address\n\nAs people often look for the copyright in files to see who to mail,\nupdate the link to a neutral one.\n\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "50be345560f1ffdcb15cc0e146416b80529a2ef2", "tree": "056278d82ea7fcbd26d9cc95c806d3978bbbb56e", "parents": [ "bcfd8d36151e531e1c6c731f1fbf792509a1c494" ], "author": { "name": "Milan Broz", "email": "mbroz@redhat.com", "time": "Mon Sep 04 15:37:57 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:52:33 2006 +0200" }, "message": "[PATCH] fix creating zero sized bio mempools in low memory system\n\nIn the very low memory systems is in the init_bio call\nscale parameter set to zero and it leads to creating\nzero sized mempool.\n\nThis patch prevents pool_entries parameter become zero,\nso the created pool have at least 1 entry.\n\nMempool with 0 entries lead to incorrect behaviour\nof mempool_free.

That,\n BTW, is a case when __nocast use had been actively confusing - it had\n been used in the same code for two different and similar types, with\n no way to catch misuses. Switch of gfp_t to bitwise had caught that\n immediately...\n\nOne tricky bit is left alone to be dealt with later - mapping-\u003eflags is\na mix of gfp_t and error indications. Left alone for now.\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "dd0fc66fb33cd610bc1a5db8a5e232d34879b4d7", "tree": "51f96a9db96293b352e358f66032e1f4ff79fafb", "parents": [ "3b0e77bd144203a507eb191f7117d2c5004ea1de" ], "author": { "name": "Al Viro", "email": "viro@ftp.linux.org.uk", "time": "Fri Oct 07 07:46:04 2005 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Oct 08 15:00:57 2005 -0700" }, "message": "[PATCH] gfp flags annotations - part 1\n\n - added typedef unsigned int __nocast gfp_t;\n\n - replaced __nocast uses for gfp flags with gfp_t - it gives exactly\n the same warnings as far as sparse is concerned, doesn\u0027t change\n generated code (from gcc point of view we replaced unsigned int with\n typedef) and documents what\u0027s going on far better.\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3f70353ea91ad77c83500e70507a239b2ab0c980", "tree": "ef51eaaa3e089c314ee3bea21ecd94d3800758ad", "parents": [ "6c9afc655d4df902211d00a437e893881cdef588" ], "author": { "name": "viro@ZenIV.linux.org.uk", "email": "viro@ZenIV.linux.org.uk", "time": "Fri Sep 09 16:53:56 2005 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 09 10:31:58 2005 -0700" }, "message": "[PATCH] bogus cast in bio.c\n\n\u003cqualifier\u003e void * is not the same as void \u003cqualifier\u003e *...\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0481990b758628e12f4b0a9e15094e70cefc7cd1", "tree": "67a4b4b7acc6a688b87ef2a2d3ec0e296e6e480c", "parents": [ "db400b3c4ee89d384d9163836a55577abdae772d", "17fa53da1239b8712c5cebbd72a74c713b6c2db9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 17:31:27 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 17:31:27 2005 -0700" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-for-linus-2.6 \n" }, { "commit": "3676347a5e216a7fec7f8eedbbcf8bed6b9c4e40", "tree": "3b5880b862390590da8edfb98c3e62aa573d0b28", "parents": [ "6f00df24ee394f345a8789d3a2f98fc1d9195b9f" ], "author": { "name": "Peter Osterlund", "email": "petero2@telia.com", "time": "Tue Sep 06 15:16:42 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 16:57:20 2005 -0700" }, "message": "[PATCH] kill bio-\u003ebi_set\n\nJens:\n\n-\u003ebi_set is totally unnecessary bloat of struct bio.
