[PATCH v1 4/6] ata: libata-scsi: improves checks for ZBC_IN and ZBC_OUT commands support

[Damien Le Moal <dlemoal@kernel.org>]

Improve ata_scsi_cmd_is_supported() to check the service action for the
ZBC_IN and ZBC_OUT opcodes, to correctly report supported zone management
commands for zoned disks.
