  "message": "[PATCH] invalidate_inode_pages2(): ignore page refcounts\n\nThe recent fix to invalidate_inode_pages() (git commit 016eb4a) managed to\nunfix invalidate_inode_pages2().\n\nThe problem is that various bits of code in the kernel can take transient refs\non pages: the page scanner will do this when inspecting a batch of pages, and\nthe lru_cache_add() batching pagevecs also hold a ref.\n\nNet result is transient failures in invalidate_inode_pages2().  This affects\nNFS directory invalidation (observed) and presumably also block-backed\ndirect-io (not yet reported).\n\nFix it by reverting invalidate_inode_pages2() back to the old version which\nignores the page refcounts.\n\nWe may come up with something more clever later, but for now we need a 2.6.18\nfix for NFS.\n\nCc: Chuck Lever \u003ccel@citi.umich.edu\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
