Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs updates from Chris Mason: "The largest set of changes here come from Miao Xie. He's cleaning up and improving read recovery/repair for raid, and has a number of related fixes. I've merged another set of fsync fixes from Filipe, and he's also improved the way we handle metadata write errors to make sure we force the FS readonly if things go wrong. Otherwise we have a collection of fixes and cleanups. Dave Sterba gets a cookie for removing the most lines (thanks Dave)" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (139 commits) btrfs: Fix compile error when CONFIG_SECURITY is not set. Btrfs: fix compiles when CONFIG_BTRFS_FS_RUN_SANITY_TESTS is off btrfs: Make btrfs handle security mount options internally to avoid losing security label. Btrfs: send, don't delay dir move if there's a new parent inode btrfs: add more superblock checks Btrfs: fix race in WAIT_SYNC ioctl Btrfs: be aware of btree inode write errors to avoid fs corruption Btrfs: remove redundant btrfs_verify_qgroup_counts declaration. btrfs: fix shadow warning on cmp Btrfs: fix compilation errors under DEBUG Btrfs: fix crash of btrfs_release_extent_buffer_page Btrfs: add missing end_page_writeback on submit_extent_page failure btrfs: Fix the wrong condition judgment about subset extent map Btrfs: fix build_backref_tree issue with multiple shared blocks Btrfs: cleanup error handling in build_backref_tree btrfs: move checks for DUMMY_ROOT into a helper btrfs: new define for the inline extent data start btrfs: kill extent_buffer_page helper btrfs: drop constant param from btrfs_release_extent_buffer_page btrfs: hide typecast to definition of BTRFS_SEND_TRANS_STUB ...
