This means\nwe tie the quota code into the VFS.  Get rid of that and make the\nfilesystem responsible for the initialization.   For most metadata operations\nthis is a straight forward move into the methods, but for truncate and\nopen it\u0027s a bit more complicated.\n\nFor truncate we currently only call vfs_dq_init for the sys_truncate case\nbecause open already takes care of it for ftruncate and open(O_TRUNC) - the\nnew code causes an additional vfs_dq_init for those which is harmless.\n\nFor open the initialization is moved from do_filp_open into the open method,\nwhich means it happens slightly earlier now, and only for regular files.\nThe latter is fine because we don\u0027t need to initialize it for operations\non special files, and we already do it as part of the namespace operations\nfor directories.\n\nAdd a dquot_file_open helper that filesystems that support generic quotas\ncan use to fill in -\u003eopen.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n"

      "message": "fs: symlink write_begin allocation context fix\n\nWith the write_begin/write_end aops, page_symlink was broken because it\ncould no longer pass a GFP_NOFS type mask into the point where the\nallocations happened.  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.
