Subject: [git pull] vfs part 3
->direct_IO() changes from Omar + saner generic_write_checks() +
dealing with fcntl()/{read,write}() races (mirroring O_APPEND/O_DIRECT
into iocb->ki_flags and instead of repeatedly looking at ->f_flags, which
can be changed by fcntl(2), check ->ki_flags - which cannot) + infrastructure
bits for dhowells' d_inode annotations + Christophs switch of /dev/loop to
vfs_iter_write().
That leaves only the actual d_inode annotations series out of the
stuff already in for-next; there are several piles of stuff from various
folks I'm going to add there tonight, leave it all to stew until the middle
of the next week or so and send the final pull request then. I hoped to do
that last bit on Monday, but since there won't be -next on Thursday and
Friday, this will probably have to happen a couple of days later ;-/
Please, pull from

Shortlog:
Al Viro (17):
new_sync_write(): discard ->ki_pos unless the return value is positive
ntfs: move iov_iter_truncate() closer to generic_write_checks()
cifs: fold cifs_iovec_write() into the only caller
__generic_file_write_iter: keep ->ki_pos and return value consistent
lift generic_write_checks() into callers of __generic_file_write_iter()
blkdev_write_iter: expand generic_file_checks() call in there
generic_write_checks(): drop isblk argument
xfs_file_aio_write_checks: switch to iocb/iov_iter
ext4_file_write_iter: move generic_write_checks() up
fuse: ->direct_IO() doesn't need generic_write_checks()
udf_file_write_iter: reorder and simplify
ocfs2_file_write_iter: stop messing with ppos
ocfs2: move generic_write_checks() before the alignment checks
switch generic_write_checks() to iocb and iter
mirror O_APPEND and O_DIRECT into iocb->ki_flags
ocfs2: use __generic_file_write_iter()
nfs: generic_write_checks() shouldn't be done on swapout...
Christoph Hellwig (1):
block: loop: switch to VFS ITER_BVEC
David Howells (7):
VFS: Add owner-filesystem positive/negative dentry checks
VFS: Impose ordering on accesses of d_inode and d_flags
NFS: Don't use d_inode as a variable name
VFS: Combine inode checks with d_is_negative() and d_is_positive() in pathwalk
VFS: Fix up debugfs to use d_is_dir() in place of S_ISDIR()
VFS: Make pathwalk use d_is_reg() rather than S_ISREG()
configfs: Fix inconsistent use of file_inode() vs file->f_path.dentry->d_inode
Omar Sandoval (5):
new helper: iov_iter_rw()
Remove rw from {,__,do_}blockdev_direct_IO()
Remove rw from dax_{do_,}io()
direct_IO: use iov_iter_rw() instead of rw everywhere
direct_IO: remove rw from a_ops->direct_IO()
