Merge tag 'pull-bd_flags-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull bdev flags update from Al Viro:
"Compactifying bdev flags.
We can easily have up to 24 flags with sane atomicity, _without_
pushing anything out of the first cacheline of struct block_device"
* tag 'pull-bd_flags-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
bdev: move ->bd_make_it_fail to ->__bd_flags
bdev: move ->bd_ro_warned to ->__bd_flags
bdev: move ->bd_has_subit_bio to ->__bd_flags
bdev: move ->bd_write_holder into ->__bd_flags
bdev: move ->bd_read_only to ->__bd_flags
bdev: infrastructure for flags
wrapper for access to ->bd_partno
Use bdev_is_paritition() instead of open-coding it
