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: (47 commits) ocfs2: Silence a gcc warning. ocfs2: Don't retry xattr set in case value extension fails. ocfs2:dlm: avoid dlm->ast_lock lockres->spinlock dependency break ocfs2: Reset xattr value size after xa_cleanup_value_truncate(). fs/ocfs2/dlm: Use kstrdup fs/ocfs2/dlm: Drop memory allocation cast Ocfs2: Optimize punching-hole code. Ocfs2: Make ocfs2_find_cpos_for_left_leaf() public. Ocfs2: Fix hole punching to correctly do CoW during cluster zeroing. Ocfs2: Optimize ocfs2 truncate to use ocfs2_remove_btree_range() instead. ocfs2: Block signals for mkdir/link/symlink/O_CREAT. ocfs2: Wrap signal blocking in void functions. ocfs2/dlm: Increase o2dlm lockres hash size ocfs2: Make ocfs2_extend_trans() really extend. ocfs2/trivial: Code cleanup for allocation reservation. ocfs2: make ocfs2_adjust_resv_from_alloc simple. ocfs2: Make nointr a default mount option ocfs2/dlm: Make o2dlm domain join/leave messages KERN_NOTICE o2net: log socket state changes ocfs2: print node # when tcp fails ...
