Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus

The big ones in that are
* ->permission() API change (death to separate boolean argument, death to
generic_permission() check_acl callback, death to file_permission(), death
to exec_permission())
* nfs4 mknod() fixes (and end to pointless carrying vfsmount pointers in the
guts of nfs)
* further reduction of struct nameidata exposure, including the LOOKUP_...
flags use
* dchinner: per-sb shrinkers
* hch: death to ->i_alloc_sem
* jbacik: SEEK_HOLE/SEEK_DATA, ->fsync() API change.

Also by jbacik: DCACHE_NEED_LOOKUP, which is going to be the basis for
atomic_open-done-right (aside of originally intended uses in btrfs).
Unfortunately, ->d_lock/->d_parent shite had sidetracked me in the last
couple of weeks of last cycle, so atomic_open will have to wait for -rc2
or -rc3; *PLEASE* hold any unionfs or overlayfs merges until then.

Other than that, there's a moderate bunch of assorted patches; I'll push
more of that in the next pull request (i.e. folks who don't see their
patches in the shortlog below, please wait for after the next vfs pull
request before complaining)

Shortlog:
Al Viro (68):
new helper: iterate_supers_type()
make exec_permission(dir) really equivalent to inode_permission(dir, MAY_EXEC)
switch udf_ioctl() to inode_permission()
switch path_init() to exec_permission()
consolidate BINPRM_FLAGS_ENFORCE_NONDUMP handling
kill file_permission() completely
move exec_permission() up to the rest of permission-related functions
lockless get_write_access/deny_write_access
kill check_acl callback of generic_permission()
->permission() sanitizing: MAY_NOT_BLOCK
->permission() sanitizing: pass MAY_NOT_BLOCK to ->check_acl()
->permission() sanitizing: don't pass flags to ->check_acl()
->permission() sanitizing: don't pass flags to generic_permission()
->permission() sanitizing: don't pass flags to ->permission()
->permission() sanitizing: don't pass flags to ->inode_permission()
selinux: don't transliterate MAY_NOT_BLOCK to IPERM_FLAG_RCU
->permission() sanitizing: don't pass flags to exec_permission()
massage generic_permission() to treat directories on a separate path
no reason to keep exec_permission() separate now
merge do_revalidate() into its only caller
->permission() sanitizing: document API changes
kill IPERM_FLAG_RCU
ecryptfs_inode_permission() doesn't need to bail out on RCU
cifs: fix the type of cifs_demultiplex_thread()
nfs4_closedata doesn't need to mess with struct path
nfs4_opendata doesn't need struct path either
nfs_open_context doesn't need struct path either
nameidata_to_nfs_open_context() doesn't need nameidata, actually...
fix mknod() on nfs4 (hopefully)
Don't pass nameidata when calling vfs_create() from mknod()
don't transliterate lower bits of ->intent.open.flags to FMODE_...
don't pass nameidata to vfs_create() from ecryptfs_create()
no need to check for LOOKUP_OPEN in ->create() instances
LOOKUP_CREATE and LOOKUP_RENAME_TARGET can be set only on the last step
jfs_ci_revalidate() is safe from RCU mode
ceph: LOOKUP_OPEN is set only when it's the last component
cifs_lookup(): LOOKUP_OPEN is set only on the last component
nfs: LOOKUP_{OPEN,CREATE,EXCL} is set only on the last step
kill LOOKUP_CONTINUE
new helpers: kern_path_create/user_path_create
switch do_spufs_create() to user_path_create(), fix double-unlock

switch vfs_path_lookup() to struct path
unexport kern_path_parent()
Make ->d_sb assign-once and always non-NULL
get rid of pointless checks for dentry->sb == NULL
btrfs: kill magical embedded struct superblock
kill useless checks for sb->s_op == NULL
nfsd4_list_rec_dir(): don't bother with reopening rec_file
deuglify squashfs_lookup()
make d_splice_alias(ERR_PTR(err), dentry) = ERR_PTR(err)
switch assorted clock drivers to debugfs_remove_recursive()
arm: don't create useless copies to pass into debugfs_create_dir()
coda_venus_readdir(): use offsetof()
minix_getattr(): don't bother with ->d_parent
don't open-code parent_ino() in assorted ->readdir()
get rid of useless dget_parent() in fs/btrfs/ioctl.c
get rid of useless dget_parent() in btrfs rename() and link()
jfs_lookup(): don't bother with . or ..
simplify gfs2_lookup()
switch d_add_ci() to d_splice_alias() in "found negative" case as well
Remove dead code in dget_parent()
fix IN_DELETE_SELF on overwriting rename() on ramfs et.al.
