Subject: zbd/002: Check validity of zone capacity
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=5768c0eff0a63f14a5a45bba595ae0c4fdbbdec9;p=users%2Fsagi%2Fblktests.git

zbd/002: Check validity of zone capacity

Linux kernel 5.9 zone descriptor interface added the new zone capacity
field defining the range of sectors usable within a zone. Add a check to
ensure that the zone capacity is smaller than or equal to the zone size.
