[git pull] vfs part 2

Now that net-next went in... Here's the next big chunk - killing
->aio_read() and ->aio_write(). There'll be one more pile today (direct_IO
changes and generic_write_checks() cleanups/fixes), but I'd prefer to keep
that one separate. Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus-2

Shortlog:
Al Viro (37):
cuse: switch to iov_iter
fuse: switch fuse_direct_io_file_operations to ->{read,write}_iter()
expand __fuse_direct_write() in both callers
lustre: kill unused members of struct vvp_thread_info
ioctx_alloc(): remove pointless check
aio_run_iocb(): kill dead check
acct: check FMODE_CAN_WRITE
nommu: use __vfs_read()
net/9p: switch the guts of p9_client_{read,write}() to iov_iter
9p: switch p9_client_write() to passing it struct iov_iter *
9p: switch ->writepage() to direct use of p9_client_write()
9p: fold v9fs_file_write_internal() into the caller
9p: get rid of v9fs_direct_file_write()
9p: switch p9_client_read() to passing struct iov_iter *
9p: get rid of v9fs_direct_file_read()
9p: switch to ->read_iter/->write_iter
9p: we are leaking glock.client_id in v9fs_file_getlock()
p9_client_attach(): set fid->uid correctly
net/9p: remove (now-)unused helpers
ncpfs: switch to ->read_iter/->write_iter
coda: switch to ->read_iter/->write_iter
switch hugetlbfs to ->read_iter()
new helper: __vfs_write()
autofs: switch to __vfs_write()
export __vfs_read()
ashmem: use __vfs_read()
serial2002: switch to __vfs_read/__vfs_write
switch /dev/loop to vfs_iter_write()
coredump: accept any write method
make new_sync_{read,write}() static
switch drivers/char/mem.c to ->read_iter/->write_iter
fuse: switch to ->read_iter/->write_iter
fuse: use iov_iter_get_pages() for non-splice path
kill do_sync_read/do_sync_write
infinibad: weird APIs switched to ->write_iter()
pcm: another weird API abuse
->aio_read and ->aio_write removed
