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_connection_find() returns pointer to bad structure ocfs2: char is not always signed Ocfs2: Stop tracking a negative dentry after dentry_iput(). ocfs2: fix memory leak fs/ocfs2/dlm: Use GFP_ATOMIC under spin_lock
