This series fixes an OOM problem where VFS-only dirty inodes accumulate on an XFS filesystem due to atime updates causing OOM to occur. The first patch fixes a deadlock triggering bdi-flusher writeback from memory reclaim when a new bdi-flusher thread needs to be forked and no memory is available. the second adds a bdi-flusher kick from XFS's inode cache shrinker so that when memory is low the VFS starts writing back dirty inodes so they can be reclaimed as they get cleaned rather than remaining dirty and pinning the inode cache in memory. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
