Subject: tests/zbd: Add tests for SCSI devices with gap zones
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=238c7e0b73468ddb26c2211095d6313c1ce0c072;p=users%2Fhch%2Fblktests.git

tests/zbd: Add tests for SCSI devices with gap zones

Verify that I/O on top of BTRFS or F2FS on top of zoned scsi_debug works
fine if gap zones are present.
