I\u0027d claim that they\n are almost impossible, unless you limit them somehow (shared\n writable mappings are the nastiest part - if you don\u0027t have those,\n you can reasonably limit your problems by limiting the number of\n dirty pages you accept through normal \"write()\" calls).\"\n\nInstead of attempting the impossible, I\u0027ve just waited for the dirty page\naccounting infrastructure to materialize (thanks to Peter Zijlstra and\nothers). This nicely solved the biggest problem: limiting the number of pages\nused for write caching.\n\nSome small details remained, however, which this largish patch attempts to\naddress. It provides a page writeback implementation for fuse, which is\ncompletely safe against VM related deadlocks. Performance may not be very\ngood for certain usage patterns, but generally it should be acceptable.\n\nIt has been tested extensively with fsx-linux and bash-shared-mapping.\n\nFuse page writeback design\n--------------------------\n\nfuse_writepage() allocates a new temporary page with GFP_NOFS|__GFP_HIGHMEM.\nIt copies the contents of the original page, and queues a WRITE request to the\nuserspace filesystem using this temp page.\n\nThe writeback is finished instantly from the MM\u0027s point of view: the page is\nremoved from the radix trees, and the PageDirty and PageWriteback flags are\ncleared.\n\nFor the duration of the actual write, the NR_WRITEBACK_TEMP counter is\nincremented. The per-bdi writeback count is not decremented until the actual\nwrite completes.\n\nOn dirtying the page, fuse waits for a previous write to finish before\nproceeding. This makes sure, there can only be one temporary page used at a\ntime for one cached page.\n\nThis approach is wasteful in both memory and CPU bandwidth, so why is this\ncomplication needed?\n\nThe basic problem is that there can be no guarantee about the time in which\nthe userspace filesystem will complete a write. It may be buggy or even\nmalicious, and fail to complete WRITE requests. We don\u0027t want unrelated parts\nof the system to grind to a halt in such cases.\n\nAlso a filesystem may need additional resources (particularly memory) to\ncomplete a WRITE request. There\u0027s a great danger of a deadlock if that\nallocation may wait for the writepage to finish.\n\nCurrently there are several cases where the kernel can block on page\nwriteback:\n\n - allocation order is larger than PAGE_ALLOC_COSTLY_ORDER\n - page migration\n - throttle_vm_writeout (through NR_WRITEBACK)\n - sync(2)\n\nOf course in some cases (fsync, msync) we explicitly want to allow blocking.\nSo for these cases new code has to be added to fuse, since the VM is not\ntracking writeback pages for us any more.\n\nAs an extra safetly measure, the maximum dirty ratio allocated to a single\nfuse filesystem is set to 1% by default. This way one (or several) buggy or\nmalicious fuse filesystems cannot slow down the rest of the system by hogging\ndirty memory.\n\nWith appropriate privileges, this limit can be raised through\n\u0027/sys/class/bdi/\u003cbdi\u003e/max_ratio\u0027.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b6f2fcbcfca9db2bd7aa24940224fcd3bbdbb8aa", "tree": "ab70a4e93c1a512f791c3a0f77810c84e2b81ef1", "parents": [ "fa799759f9801137f665dbedda2c0815f1bf6f1b" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Wed Apr 30 00:54:34 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:49 2008 -0700" }, "message": "mm: bdi: expose the BDI object in sysfs for FUSE\n\nRegister FUSE\u0027s backing_dev_info under sysfs with the name \"fuse-MAJOR:MINOR\"\n\nMake the fuse control filesystem use s_dev instead of a fuse specific ID.\nThis makes it easier to match directories under /sys/fs/fuse/connections/ with\ndirectories under /sys/class/bdi, and with actual mounts.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "42faad99658eed7ca8bd328ffa4bcb7d78c9bcca", "tree": "8b57fb69d1922939c6ba13f512a0ae54a3a171ef", "parents": [ "78d31a3a87f84cf56004b7bc154831f2ee1186e8" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu Apr 24 07:21:56 2008 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Fri Apr 25 09:23:25 2008 -0400" }, "message": "[PATCH] restore sane -\u003eumount_begin() API\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "d1875dbaa58e4894f7d9321d1c280fb23ca9f9e5", "tree": "dffcd7b60e50a1bcd112795e2a438c254b12f870", "parents": [ "c1fca3b6090f45018b3754eff0276521edb8ac3e" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Fri Feb 08 04:21:43 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:40 2008 -0800" }, "message": "mount options: fix fuse\n\nAdd blksize\u003d option to /proc/mounts for fuseblk filesystems.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fa300b1914f892196acb385677047bc978466de7", "tree": "58729e181e2a7aca020d3079eadbf1b718e40c1f", "parents": [ "d0b079483dd4cf6373f0ff234d5fdaef80c9588f" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Feb 07 00:15:40 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Feb 07 08:42:28 2008 -0800" }, "message": "iget: stop FUSE from using iget() and read_inode()\n\nStop the FUSE filesystem from using read_inode(), which it doesn\u0027t use anyway.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nAcked-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d12def1bcb809b6172ee207a24e00a0a4398df1d", "tree": "96e151de1e80cacd9202a00b77654533a9754207", "parents": [ "b57d426445c98789265de6a9338cdb06462d15fb" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Wed Feb 06 01:38:39 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Feb 06 10:41:13 2008 -0800" }, "message": "fuse: limit queued background requests\n\nLibfuse basically creates a new thread for each new request.

So fuse mounts would look like this:\n\n /dev/hda1 /mnt/windows fuseblk.ntfs-3g rw,...\n user@server:/ /mnt/server fuse.sshfs rw,nosuid,nodev,...\n\nThis patch adds the necessary code to the kernel so that this can be\ncorrectly displayed in /proc/mounts.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "50953fe9e00ebbeffa032a565ab2f08312d51a87", "tree": "9f95f56f0b51600959a76cd88ce17f6e9c7a98a3", "parents": [ "4b1d89290b62bb2db476c94c82cf7442aab440c8" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Sun May 06 14:50:16 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon May 07 12:12:57 2007 -0700" }, "message": "slab allocators: Remove SLAB_DEBUG_INITIAL flag\n\nI have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by\nSLAB.\n\nI think its purpose was to have a callback after an object has been freed\nto verify that the state is the constructor state again? The callback is\nperformed before each freeing of an object.\n\nI would think that it is much easier to check the object state manually\nbefore the free. That also places the check near the code object\nmanipulation of the object.\n\nAlso the SLAB_DEBUG_INITIAL callback is only performed if the kernel was\ncompiled with SLAB debugging on. If there would be code in a constructor\nhandling SLAB_DEBUG_INITIAL then it would have to be conditional on\nSLAB_DEBUG otherwise it would just be dead code. But there is no such code\nin the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real\nuse of, difficult to understand and there are easier ways to accomplish the\nsame effect (i.e. add debug code before kfree).\n\nThere is a related flag SLAB_CTOR_VERIFY that is frequently checked to be\nclear in fs inode caches. Remove the pointless checks (they would even be\npointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors.\n\nThis is the last slab flag that SLUB did not support. Remove the check for\nunimplemented flags from SLUB.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "823bccfc4002296ba88c3ad0f049e1abd8108d30", "tree": "5338ae0b32409446af4cd00c5107d9405d5bf0b6", "parents": [ "2609e7b9bebfd433254c02538ba803dc516ff674" ], "author": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri Apr 13 13:15:19 2007 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed May 02 18:57:59 2007 -0700" }, "message": "remove \"struct subsystem\" as it is no longer needed\n\nWe need to work on cleaning up the relationship between kobjects, ksets and\nktypes.
