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.
