Damien Le Moal 5486888fbd block: Introduce bio_needs_zone_write_plugging() ... commit f70291411b upstream. In preparation for fixing device mapper zone write handling, introduce the inline helper function bio_needs_zone_write_plugging() to test if a BIO requires handling through zone write plugging using the function blk_zone_plug_bio(). This function returns true for any write (op_is_write(bio) == true) operation directed at a zoned block device using zone write plugging, that is, a block device with a disk that has a zone write plug hash table. This helper allows simplifying the check on entry to blk_zone_plug_bio() and used in to protect calls to it for blk-mq devices and DM devices.
