Subject[PATCH 5.5 183/257] dm zoned: remove duplicate nr_rnd_zones increase in dmz_init_zone()
Date
From: Bob Liu <bob.liu@oracle.com>

commit b8fdd090376a7a46d17db316638fe54b965c2fb0 upstream.

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")
