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": "097b8457dafe7efc22201b4062e2d1e82e494067", "tree": "c59484ba7965d4e18bff2e6492d296382cbf86ac", "parents": [ "ae56fb16337c882c52806508f93ead4034004c7a" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Thu Nov 16 01:19:31 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Nov 16 11:43:38 2006 -0800" }, "message": "[PATCH] scsi: clear garbage after CDBs on SG_IO\n\nATAPI devices transfer fixed number of bytes for CDBs (12 or 16).

Not all embedded devices require\nit, some can make do with just JFFS2, NFS, ramfs, etc - none of which require\nthe block layer to be present.\n\nThis patch does the following:\n\n (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev\n support.\n\n (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls\n an item that uses the block layer. This includes:\n\n (*) Block I/O tracing.\n\n (*) Disk partition code.\n\n (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.\n\n (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the\n \t block layer to do scheduling. Some drivers that use SCSI facilities -\n \t such as USB storage - end up disabled indirectly from this.\n\n (*) Various block-based device drivers, such as IDE and the old CDROM\n \t drivers.\n\n (*) MTD blockdev handling and FTL.\n\n (*) JFFS - which uses set_bdev_super(), something it could avoid doing by\n \t taking a leaf out of JFFS2\u0027s book.\n\n (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and\n linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is,\n however, still used in places, and so is still available.\n\n (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and\n parts of linux/fs.h.\n\n (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.\n\n (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.\n\n (*) set_page_dirty() doesn\u0027t call __set_page_dirty_buffers() if CONFIG_BLOCK\n is not enabled.\n\n (*) fs/no-block.c is created to hold out-of-line stubs and things that are\n required when CONFIG_BLOCK is not set:\n\n (*) Default blockdev file operations (to give error ENODEV on opening).\n\n (*) Makes some /proc changes:\n\n (*) /proc/devices does not list any blockdevs.\n\n (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.\n\n (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.\n\n (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if\n given command other than Q_SYNC or if a special device is specified.\n\n (*) In init/do_mounts.c, no reference is made to the blockdev routines if\n CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2.\n\n (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return\n error ENOSYS by way of cond_syscall if so).\n\n (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if\n CONFIG_BLOCK is not set, since they can\u0027t then happen.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "4090959aee403817ff386415f9bc602c1a0882ef", "tree": "e2bd8b6ea922b14def3309eb18fc7d469e635b90", "parents": [ "cf342e52e3117391868fb4bd900ce772a27a5a1a" ], "author": { "name": "Martin Peschke", "email": "mp3@de.ibm.com", "time": "Tue Aug 29 19:52:55 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:31:19 2006 +0200" }, "message": "[PATCH] blktrace: cleanup using on_each_cpu\n\nThis patch kills a few lines of code in blktrace by making use of\non_each_cpu().\n\nSigned-off-by: Martin Peschke \u003cmp3@de.ibm.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "25034d7a83cf77667f3d65822484b305d4be6b25", "tree": "7e4d432aae0cab93c22e692ceceffe2b5f7500d6", "parents": [ "9bf09c23853bb8009625c2ec60dc6beb9472d3ca" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Tue Aug 29 09:15:14 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:31:18 2006 +0200" }, "message": "[PATCH] exit_io_context: don\u0027t disable irqs\n\nWe don\u0027t need to disable irqs to clear current-\u003eio_context, it is protected\nby -\u003ealloc_lock.

This is a 10% reduction\nin the inode size on a UP kernel that is configured in a production mode\n(i.e., with no spinlock or other debugging functions enabled; if you want to\nsave memory taken up by in-core inodes, the first thing you should do is\ndisable the debugging options; they are responsible for a huge amount of bloat\nin the VFS inode structure).\n\nThis patch:\n\nThe filesystem or device-specific pointer in the inode is inside a union,\nwhich is pretty pointless given that all 30+ users of this field have been\nusing the void pointer. Get rid of the union and rename it to i_private, with\na comment to explain who is allowed to use the void pointer. This is just a\ncleanup, but it allows us to reuse the union \u0027u\u0027 for something something where\nthe union will actually be used.\n\n[judith@osdl.org: powerpc build fix]\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nSigned-off-by: Judith Lebzelter \u003cjudith@osdl.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1aedf2ccc60fade26c46fae12e28664d0da3f199", "tree": "d91083e3079f1ddb942a382ac2b5a7525570ad59", "parents": [ "dfdc58ba354adb80d67c99f7be84f95a8e02e466", "1ab9dd0902df4f4ff56fbf672220549090ab28ba" ], "author": { "name": "James Bottomley", "email": "jejb@sparkweed.localdomain", "time": "Sat Sep 23 21:03:52 2006 -0500" }, "committer": { "name": "James Bottomley", "email": "jejb@sparkweed.localdomain", "time": "Sat Sep 23 21:03:52 2006 -0500" }, "message": "Merge mulgrave-w:git/linux-2.6\n\nConflicts:\n\n\tinclude/linux/blkdev.h\n\nTrivial merge to incorporate tag prototypes.\n" }, { "commit": "275a082fe9308e710324e26ccb5363c53d8fd45f", "tree": "e97df6e45f98ea2827f71dc749f8cd47f3f353cc", "parents": [ "94a6d75320b3681e6e728b70e18bd186cb55e682" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Tue Aug 22 20:06:24 2006 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Sep 22 23:24:54 2006 -0400" }, "message": "Add a real API for dealing with blk_congestion_wait()\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "492dfb489658dfe4a755fa29dd0e34e9c8bd8fb8", "tree": "1ad52b1ce98743729c7cacce0c602e22d3a5d076", "parents": [ "f19eaa7f53736449a6eac89c3863eca2c64d5913" ], "author": { "name": "James Bottomley", "email": "James.Bottomley@steeleye.com", "time": "Wed Aug 30 15:48:45 2006 -0400" }, "committer": { "name": "James Bottomley", "email": "jejb@mulgrave.il.steeleye.com", "time": "Thu Aug 31 11:17:18 2006 -0400" }, "message": "[SCSI] block: add support for shared tag maps\n\nThe current block queue implementation already contains most of the\nmachinery for shared tag maps.
