Message-ID: <20130227032406.GM4503@ZenIV.linux.org.uk>
Date: Wed, 27 Feb 2013 03:24:06 +0000
From: Al Viro <viro@...IV.linux.org.uk>
To: Linus Torvalds <torvalds@...ux-foundation.org>
Cc: linux-kernel@...r.kernel.org, linux-fsdevel@...r.kernel.org
Subject: [git pull] vfs pile 1
Assorted stuff - cleaning namei.c up a bit, fixing ->d_name/->d_parent
locking violations, etc. The most visible changes here are death of
FS_REVAL_DOT (replaced with "has ->d_weak_revalidate()") and a new helper
getting from struct file to inode. Some bits of preparation to xattr
method interface changes. Misc patches by various people sent this cycle
*and* ocfs2 fixes from several cycles ago that should've been upstream right
then.
Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus
PS: the next vfs pile will be xattr stuff.
Shortlog:
Al Viro (33):
mount: consolidate permission checks
new helper: file_inode(file)
propagate error from get_empty_filp() to its callers
clean shmem_file_setup() a bit
link_path_walk(): move assignments to nd->last/nd->last_type up
get rid of name and type arguments of walk_component()
lookup_fast: get rid of name argument
lookup_slow: get rid of name argument
constify __d_lookup() arguments
constify d_lookup() arguments
__d_materialise_unique() is too generic
xenfs: switch to pure simple_fill_super()
hostfs: directory methods have no business in non-directory inode_operations
spufs_mkdir(): don't d_add() on negative parent
oprofilefs: add missing ->i_mutex locking in object creation
shmem_setup_file(): use d_alloc_pseudo() instead of d_alloc()
hugetlb_file_setup(): use d_alloc_pseudo()
lirc: get rid of bogus checks
tegra: don't wank with d_find_alias()
9p: add fid-based variant of v9fs_xattr_set()
9p: lift the call of set_cached_acl() into the callers of v9fs_set_acl()
9p: switch v9fs_set_acl() from dentry to fid
9p: switch v9fs_acl_chmod() from dentry to inode+fid
9p: split dropping the acls from v9fs_set_create_acl()
9p: switch v9fs_set_create_acl() to inode+fid, do it before d_instantiate()
d_hash_and_lookup(): export, switch open-coded instances
default SET_PERSONALITY() in linux/elf.h
switch vfs_getattr() to struct path
kill f_vfsmnt
export kernel_write(), convert open-coded instances
target: writev() on single-element vector is pointless
get_empty_filp()/alloc_file() leave both ->f_pos and ->f_version zero
saner proc_get_inode() calling conventions
Anatol Pomozov (1):
fs: Preserve error code in get_empty_filp(), part 2
Dan Carpenter (1):
ocfs2/dlm: use GFP_ATOMIC inside a spin_lock
J. Bruce Fields (1):
nfsd: handle vfs_getattr errors in acl protocol
Jan Kara (2):
fs: Fix possible use-after-free with AIO
ocfs2: fix possible use-after-free with AIO
Jeff Layton (2):
vfs: remove d_path_with_unreachable
vfs: kill FS_REVAL_DOT by adding a d_weak_revalidate dentry op
Maxim Patlasov (1):
proc: avoid extra pde_put() in proc_fill_super()
Namjae Jeon (1):
fs: encode_fh: return FILEID_INVALID if invalid fid_type
Sage Weil (1):
ceph: prepopulate inodes only when request is aborted
Sunil Mushran (1):
ocfs2: Fix oops in ocfs2_fast_symlink_readpage() code path
Yuanhan Liu (1):
fs/exec.c: make bprm_mm_init() static
Zhao Hongjiang (1):
fs: change return values from -EACCES to -EPERM
