Merge branch 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jlbec/ocfs2
* 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jlbec/ocfs2: ocfs2: Fix a race in o2dlm lockres mastery Ocfs2: Handle deletion of reflinked oprhan inodes correctly. Ocfs2: Journaling i_flags and i_orphaned_slot when adding inode to orphan dir. ocfs2: Clear undo bits when local alloc is freed ocfs2: Init meta_ac properly in ocfs2_create_empty_xattr_block. ocfs2: Fix the update of name_offset when removing xattrs ocfs2: Always try for maximum bits with new local alloc windows ocfs2: set i_mode on disk during acl operations ocfs2: Update i_blocks in reflink operations. ocfs2: Change bg_chain check for ocfs2_validate_gd_parent. [PATCH] Skip check for mandatory locks when unlocking
