They are done in write_begin, which would always\nassume that the filesystem can be entered from reclaim. This bug could\ncause filesystem deadlocks.\n\nThe funny thing with having a gfp_t mask there is that it doesn\u0027t really\nallow the caller to arbitrarily tinker with the context in which it can be\ncalled. It couldn\u0027t ever be GFP_ATOMIC, for example, because it needs to\ntake the page lock. The only thing any callers care about is __GFP_FS\nanyway, so turn that into a single flag.\n\nAdd a new flag for write_begin, AOP_FLAG_NOFS. Filesystems can now act on\nthis flag in their write_begin function. Change __grab_cache_page to\naccept a nofs argument as well, to honour that flag (while we\u0027re there,\nchange the name to grab_cache_page_write_begin which is more instructive\nand does away with random leading underscores).\n\nThis is really a more flexible way to go in the end anyway -- if a\nfilesystem happens to want any extra allocations aside from the pagecache\nones in ints write_begin function, it may now use GFP_KERNEL (rather than\nGFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a\nrandom example).\n\n[kosaki.motohiro@jp.fujitsu.com: fix ubifs]\n[kosaki.motohiro@jp.fujitsu.com: fix fuse]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: \u003cstable@kernel.org\u003e\t\t[2.6.28.x]\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n[ Cleaned up the calling convention: just pass in the AOP flags\n untouched to the grab_cache_page_write_begin() function.

This list can be very long if there is huge free memory.\n\n- the problem\n\n When shrink_dcache_sb() is called, it scans all dentry_unused linearly\n under spin_lock(), and if dentry-\u003ed_sb is differnt from given\n superblock, scan next dentry. This scan costs very much if there are\n many entries, and very ineffective if there are many superblocks.\n\n IOW, When we need to shrink unused dentries on one dentry, but scans\n unused dentries on all superblocks in the system. For example, we scan\n 500 dentries to unmount a filesystem, but scans 1,000,000 or more unused\n dentries on other superblocks.\n\n In our case , At mounting NFS*, shrink_dcache_sb() is called to shrink\n unused dentries on NFS, but scans 100,000,000 unused dentries on\n superblocks in the system such as local ext3 filesystems. I hear NFS\n mounting took 1 min on some system in use.\n\n* : NFS uses virtual filesystem in rpc layer, so NFS is affected by\n this problem.\n\n 100,000,000 is possible number on large systems.\n\n Per-superblock LRU of unused dentried can reduce the cost in\n reasonable manner.\n\n- How to fix\n\n I found this problem is solved by David Chinner\u0027s \"Per-superblock\n unused dentry LRU lists V3\"(1), so I rebase it and add some fix to\n reclaim with fairness, which is in Andrew Morton\u0027s comments(2).\n\n 1) http://lkml.org/lkml/2006/5/25/318\n 2) http://lkml.org/lkml/2006/5/25/320\n\n Split LRU-list of unused dentries to each superblocks. Then, NFS\n mounting will check dentries under a superblock instead of all. But\n this spliting will break LRU of dentry-unused. So, I\u0027ve attempted to\n make reclaim unused dentrins with fairness by calculate number of\n dentries to scan on this sb based on following way\n\n number of dentries to scan on this sb \u003d\n count * (number of dentries on this sb / number of dentries in the machine)\n\n- ToDo\n - I have to measuring performance number and do stress tests.\n\n - When unmount occurs during prune_dcache(), scanning on same\n superblock, It is unable to reach next superblock because it is gone\n away. We restart scannig superblock from first one, it causes\n unfairness of reclaim unused dentries on first superblock. But I think\n this happens very rarely.\n\n- Test Results\n\n Result on 6GB boxes with excessive unused dentries.\n\nWithout patch:\n\n$ cat /proc/sys/fs/dentry-state\n10181835 10180203 45 0 0 0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal 0m1.830s\nuser 0m0.001s\nsys 0m1.653s\n\n With this patch:\n$ cat /proc/sys/fs/dentry-state\n10236610 10234751 45 0 0 0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal 0m0.106s\nuser 0m0.002s\nsys 0m0.032s\n\n[akpm@linux-foundation.org: fix comments]\nSigned-off-by: Kentaro Makita \u003ck-makita@np.css.fujitsu.com\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: David Chinner \u003cdgc@sgi.com\u003e\nCc: \"J.

I changed the file systems who don\u0027t use the BKL\nfor anything (CIFS, GFS) to call it directly. NCPFS and SMBFS and NFS\ntake the BKL, but explicitely in their own source now.\n\nI moved them all over in a single patch to avoid unbisectable sections.\n\nOpen problem: 32bit kernels can corrupt fpos because its modification\nis not atomic, but they can do that anyways because there\u0027s other paths who\nmodify it without BKL.\n\nDo we need a special lock for the pos/f_version \u003d 0 checks?\n\nTrond says the NFS BKL is likely not needed, but keep it for now\nuntil his full audit.\n\nv2: Use generic_file_llseek_unlocked instead of remote_llseek_unlocked\n and factor duplicated code (suggested by hch)\n\nCc: Trond.Myklebust@netapp.com\nCc: swhiteho@redhat.com\nCc: sfrench@samba.org\nCc: vandrove@vc.cvut.cz\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\nSigned-off-by: Jonathan Corbet \u003ccorbet@lwn.net\u003e\n" }, { "commit": "18ce3751ccd488c78d3827e9f6bf54e6322676fb", "tree": "4bb83c2b963e8ebe918b79f61d1a440fb1d28f8d", "parents": [ "d585d0b9d73ed999cc7b8cf3cac4a5b01abb544e" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Jul 01 09:07:34 2008 +0200" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Jul 01 09:07:34 2008 +0200" }, "message": "Properly notify block layer of sync writes\n\nfsync_buffers_list() and sync_dirty_buffer() both issue async writes and\nthen immediately wait on them.
