this list for\neach group, and a common code flow to remove an album is like\nthis:\n\n ext4_get_group_no_and_offset(sb, pa-\u003epa_pstart, \u0026grp, NULL);\n ext4_lock_group(sb, grp);\n

\nassociated with this pa) and prevent concurrent list manipulation.\n\nhowever, ext4_mb_put_pa() passes in (pa-\u003epa_pstart - 1) with a \ncomment, \"-1 is to protect from crossing allocation group\".\n\nThis makes sense for the group_pa, where pa_pstart is advanced\nby the length which has been used (in ext4_mb_release_context()),\nand when the entire length has been used, pa_pstart has been\nadvanced to the first block of the next group.\n\nHowever, for inode_pa, pa_pstart is never advanced; it\u0027s just\nset once to the first block in the group and not moved after\nthat.

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.
