Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs fixes from Al Viro. Clean up file table accesses (get rid of fget_light() in favor of the fdget() interface), add proper file position locking. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: get rid of fget_light() sockfd_lookup_light(): switch to fdget^W^Waway from fget_light vfs: atomic f_pos accesses as per POSIX ocfs2 syncs the wrong range...
