Merge tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw
Pull gfs2 updates from Steven Whitehouse: "This time we have mostly clean ups. There is a bug fix for a NULL dereference relating to ACLs, and another which improves (but does not fix entirely) an allocation fall-back code path. The other three patches are small clean ups" * tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw: GFS2: Fix crash during ACL deletion in acl max entry check in gfs2_set_acl() GFS2: use __vmalloc GFP_NOFS for fs-related allocations. GFS2: Eliminate a nonsense goto GFS2: fix sprintf format specifier GFS2: Eliminate __gfs2_glock_remove_from_lru
