Merge tag 'pull-set_blocksize' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs blocksize updates from Al Viro:
"This gets rid of bogus set_blocksize() uses, switches it over
to be based on a 'struct file *' and verifies that the caller
has the device opened exclusively"
* tag 'pull-set_blocksize' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
make set_blocksize() fail unless block device is opened exclusive
set_blocksize(): switch to passing struct file *
btrfs_get_bdev_and_sb(): call set_blocksize() only for exclusive opens
swsusp: don't bother with setting block size
zram: don't bother with reopening - just use O_EXCL for open
swapon(2): open swap with O_EXCL
swapon(2)/swapoff(2): don't bother with block size
pktcdvd: sort set_blocksize() calls out
bcache_register(): don't bother with set_blocksize()
