From: Niklas Cassel <niklas.cassel@xxxxxxx> Allow the following blk-zoned ioctls: BLKREPORTZONE, BLKRESETZONE, BLKOPENZONE, BLKCLOSEZONE, and BLKFINISHZONE to be performed without CAP_SYS_ADMIN. Neither read() nor write() requires CAP_SYS_ADMIN, and considering the close relationship between read()/write() and these ioctls, there is no reason to require CAP_SYS_ADMIN for these ioctls either. Changes since v2: -Drop the FMODE_READ check from patch 2/2. Right now it is possible to open() the device with O_WRONLY and get the zone report from that fd. Therefore adding a FMODE_READ check on BLKREPORTZONE would break existing applications. Instead, just remove the existing CAP_SYS_ADMIN check.
