Pull second try at vfs part d#2 from Al Viro: "Miklos' first series (with do_lookup() rewrite split into edible chunks) + assorted bits and pieces. The 'untangling of do_lookup()' series is is a splitup of what used to be a monolithic patch from Miklos, so this series is basically "how do I convince myself that his patch is correct (or find a hole in it)". No holes found and I like the resulting cleanup, so in it went..." Changes from try 1: Fix a boot problem with selinux, and commit messages prettied up a bit. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (24 commits) vfs: fix out-of-date dentry_unhash() comment vfs: split __lookup_hash untangling do_lookup() - take __lookup_hash()-calling case out of line. untangling do_lookup() - switch to calling __lookup_hash() untangling do_lookup() - merge d_alloc_and_lookup() callers untangling do_lookup() - merge failure exits in !dentry case untangling do_lookup() - massage !dentry case towards __lookup_hash() untangling do_lookup() - get rid of need_reval in !dentry case untangling do_lookup() - eliminate a loop. untangling do_lookup() - expand the area under ->i_mutex untangling do_lookup() - isolate !dentry stuff from the rest of it. vfs: move MAY_EXEC check from __lookup_hash() vfs: don't revalidate just looked up dentry vfs: fix d_need_lookup/d_revalidate order in do_lookup ext3: move headers to fs/ext3/ migrate ext2_fs.h guts to fs/ext2/ext2.h new helper: ext2_image_size() get rid of pointless includes of ext2_fs.h ext2: No longer export ext2_fs.h to user space mtdchar: kill persistently held vfsmount ...
