In balance_pgdat, we keep a separate\npriority record per zone in a local array. In try_to_free_pages there is\nno need to do this, as the priority level is the same for all zones that we\nreclaim from.\n\nImpact of this bug is that temp_priority is copied into prev_priority, and\nsetting this artificially high causes reclaimers to set distress\nartificially low.

We simply use the\ninode number and generation number to construct the filehandle.\n\nThe generation number is the time when the file was created. As inode numbers\ncycle through the full 32 bits before being reused, there is no real chance of\nthe same inum being allocated to different files in the same second so this is\nsuitably unique. Using time-of-day rather than e.g. jiffies makes it less\nlikely that the same filehandle can be created after a reboot.\n\nIn order to be able to decode a filehandle we need to be able to lookup by\ninum, which means that the inode needs to be added to the inode hash table\n(tmpfs doesn\u0027t currently hash inodes as there is never a need to lookup by\ninum). To avoid overhead when not exporting, we only hash an inode when it is\nfirst exported. This requires a lock to ensure it isn\u0027t hashed twice.\n\nThis code is separate from the patch posted in June06 from Atal Shargorodsky\nwhich provided the same functionality, but does borrow slightly from it.\n\nLocking comment: Most filesystems that hash their inodes do so at the point\nwhere the \u0027struct inode\u0027 is initialised, and that has suitable locking\n(I_NEW). Here in shmem, we are hashing the inode later, the first time we\nneed an NFS file handle for it.

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": "811d736f9e8013966e1a5a930c0db09508bdbb15", "tree": "566225f7991f987007ccc2e8d99255f21041b6cb", "parents": [ "7b0de42d7c5a471741ede4e71727d88000e6ea59" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Aug 29 19:06:09 2006 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:52:26 2006 +0200" }, "message": "[PATCH] BLOCK: Dissociate generic_writepages() from mpage stuff [try #6]\n\nDissociate the generic_writepages() function from the mpage stuff, moving its\ndeclaration to linux/mm.h and actually emitting a full implementation into\nmm/page-writeback.c.\n\nThe implementation is a partial duplicate of mpage_writepages() with all BIO\nreferences removed.\n\nIt is used by NFS to do writeback.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "831058dec3735665fe91bd0d37b6a8cf56b91abd", "tree": "5ef7d38d9c43b24d5a31eb8f0e23c91e20e799e7", "parents": [ "b398f6bff93a247d2a7099e92905374966e4558f" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Aug 29 19:06:00 2006 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:32:11 2006 +0200" }, "message": "[PATCH] BLOCK: Separate the bounce buffering code from the highmem code [try #6]\n\nMove the bounce buffer code from mm/highmem.c to mm/bounce.c so that it can be\nmore easily disabled when the block layer is disabled.\n\n!!!NOTE!!!

Make this top cpus file read-only.\n\nOn systems that have cpusets configured in their kernel, but that aren\u0027t\nactively using cpusets (for some distros, this covers the majority of\nsystems) all tasks end up in the top cpuset.\n\nIf that system does support memory hotplug, then these tasks cannot make\nuse of memory nodes that are added after system boot, because the memory\nnodes are not allowed in the top cpuset. This is a surprising regression\nover earlier kernels that didn\u0027t have cpusets enabled.\n\nOne key motivation for this change is to remain consistent with the\nbehaviour for the top_cpuset\u0027s \u0027cpus\u0027, which is also read-only, and which\nautomatically tracks the cpu_online_map.\n\nThis change also has the minor benefit that it fixes a long standing,\nlittle noticed, minor bug in cpusets. The cpuset performance tweak to\nshort circuit the cpuset_zone_allowed() check on systems with just a single\ncpuset (see \u0027number_of_cpusets\u0027, in linux/cpuset.h) meant that simply\nchanging the \u0027mems\u0027 of the top_cpuset had no affect, even though the change\n(the write system call) appeared to succeed. With the following change,\nthat write to the \u0027mems\u0027 file fails -EACCES, and the \u0027mems\u0027 file stubbornly\nrefuses to be changed via user space writes. Thus no one should be mislead\ninto thinking they\u0027ve changed the top_cpusets\u0027s \u0027mems\u0027 when in affect they\nhaven\u0027t.\n\nIn order to keep the behaviour of cpusets consistent between systems\nactively making use of them and systems not using them, this patch changes\nthe behaviour of the \u0027mems\u0027 file in the top (root) cpuset, making it read\nonly, and making it automatically track the value of node_online_map. Thus\ntasks in the top cpuset will have automatic use of hot plugged memory nodes\nallowed by their cpuset.\n\n[akpm@osdl.org: build fix]\n[bunk@stusta.de: build fix]\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b78483a4ba60d5d90930262a533a784e1d9df660", "tree": "0b2cb0f3cf2852bf4138c13179221e58a37f402a", "parents": [ "01017a227044d64face2588fab9427a1da1bdb9f" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Fri Sep 29 02:01:14 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:21 2006 -0700" }, "message": "[PATCH] oom: don\u0027t kill current when another OOM in progress\n\nA previous patch to allow an exiting task to OOM kill itself (and thereby\navoid a little deadlock) introduced a problem.
