Subject: [PATCH 0/2] allow blk-zoned ioctls without CAP_SYS_ADMIN

From: Niklas Cassel <niklas.cassel@....com>

Allow the following blk-zoned ioctls: BLKREPORTZONE, BLKRESETZONE,
BLKOPENZONE, BLKCLOSEZONE, and BLKFINISHZONE to be performed without
CAP_SYS_ADMIN.

These ioctls instead only requires that the corresponding R/W access
control flag to be successfully set on the opened file descriptor.

(open()/openat() will fail with -EPERM if you try to open a file with
flags that you lack permission for.)

Niklas Cassel (2):
  blk-zoned: allow zone management send operations without CAP_SYS_ADMIN
  blk-zoned: allow BLKREPORTZONE without CAP_SYS_ADMIN
