Merge branch 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull second vfs update from Al Viro: "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" * 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (37 commits) ->aio_read and ->aio_write removed pcm: another weird API abuse infinibad: weird APIs switched to ->write_iter() kill do_sync_read/do_sync_write fuse: use iov_iter_get_pages() for non-splice path fuse: switch to ->read_iter/->write_iter switch drivers/char/mem.c to ->read_iter/->write_iter make new_sync_{read,write}() static coredump: accept any write method switch /dev/loop to vfs_iter_write() serial2002: switch to __vfs_read/__vfs_write ashmem: use __vfs_read() export __vfs_read() autofs: switch to __vfs_write() new helper: __vfs_write() switch hugetlbfs to ->read_iter() coda: switch to ->read_iter/->write_iter ncpfs: switch to ->read_iter/->write_iter net/9p: remove (now-)unused helpers p9_client_attach(): set fid->uid correctly ...
