Subject: block: call blk_queue_free_zone_bitmaps from disk_release
X-Git-Tag: v6.1-rc5~768^2~118
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6cc37a672a1e21245b931722a016b3bd4ae10e2d;p=platform%2Fkernel%2Flinux-starfive.git

block: call blk_queue_free_zone_bitmaps from disk_release

The zone bitmaps are only used for non-passthrough I/O, so free them as
soon as the disk is released.
