While\nthis is compliant with all of the current protocol\nspecifications, there are servers in the market which can not\nhandle out of order WRITE requests very well. Also, this may\nlead to sub-optimal block allocations in the underlying file\nsystem on the server. This may cause the read throughputs to\nbe reduced when reading the file from the server.\n\nPeter: There has been a lot of work recently done to address out of\norder issues on a systemic level. However, the NFS client is\nstill susceptible to the problem. Out of order WRITE\nrequests can occur when pdflush is in the middle of writing\nout pages while the process dirtying the pages calls\ngeneric_file_buffered_write which calls\ngeneric_perform_write which calls\nbalance_dirty_pages_rate_limited which ends up calling\nwriteback_inodes which ends up calling back into the NFS\nclient to writes out dirty pages for the same file that\npdflush happens to be working with.\n\nSigned-off-by: Peter Staubach \u003cstaubach@redhat.com\u003e\n[modification by Trond to merge the two similar patches]\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "fb8a1f11b64e213d94dfa1cebb2a42a7b8c115c4", "tree": "4b21038fae0e1a8a763d4118bd6543dc77e9b5aa", "parents": [ "a65318bf3afc93ce49227e849d213799b072c5fd" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 11 14:10:29 2009 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 11 14:10:29 2009 -0400" }, "message": "NFS: cleanup - remove struct nfs_inode-\u003encommit\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "a65318bf3afc93ce49227e849d213799b072c5fd", "tree": "754aad8596310825b96956012b7f584fff5b7a54", "parents": [ "69aaaae18f7027d9594bce100378f102926cc0be" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 11 14:10:28 2009 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 11 14:10:28 2009 -0400" }, "message": "NFSv4: Simplify some cache consistency post-op GETATTRs\n\nCertain asynchronous operations such as write() do not expect\n(or care) that other metadata such as the file owner, mode, acls, ...\nchange.

On the server do a \"stat ~/.Xauthority\"\n6. Now on the client, try to open xterm\nThis will fail.\n\nEven if the filehandle had become stale, the NFS client should invalidate\nthe cache/inode and should repeat LOOKUP. Looking at the packet capture when\nthe failure occurs shows that there were two subsequent ACCESS() calls with\nthe same filehandle and both fails with -ESTALE error.\n\nI have tested the fix below. Now the client issue a LOOKUP after the\nACCESS() call fails with -ESTALE. If all this makes sense to you, can you\nconsider this for inclusion?\n\nThanks,\n\n\nIf the server returns an -ESTALE error due to stale filehandle in response to\nan ACCESS() call, we need to invalidate the cache and inode so that LOOKUP()\ncan be retried.

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.

It is assuming that the cache is valid in the\nregion, [read_cache_jiffies, read_cache_jiffies + attrtimeo]. The\ncache should be considered valid only in the region,\n[read_cache_jiffies, read_cache_jiffies + attrtimeo).
