    Subject[PATCH 4.19 133/146] dm zoned: remove duplicate nr_rnd_zones increase in dmz_init_zone()
    Date
    From: Bob Liu <bob.liu@oracle.com>

    [ Upstream commit b8fdd090376a7a46d17db316638fe54b965c2fb0 ]

    zmd->nr_rnd_zones was increased twice by mistake. The other place it
    is increased in dmz_init_zone() is the only one needed:

    1131 zmd->nr_useable_zones++;
    1132 if (dmz_is_rnd(zone)) {
    1133 zmd->nr_rnd_zones++;
    ^^^
    Fixes: 3b1a94c88b79 ("dm zoned: drive-managed zoned block device target")
