Subject: [PATCH] btrfs: send: return EOPNOTSUPP on unknown flags
Date: Wed, 10 Jan 2024 17:55:50 +0100 [thread overview]
Message-ID: <20240110165550.1701-1-dsterba@suse.com> (raw)
When some ioctl flags are checked we return EOPNOTSUPP, like for
BTRFS_SCRUB_SUPPORTED_FLAGS, BTRFS_SUBVOL_CREATE_ARGS_MASK or fallocate
modes. The EINVAL is supposed to be for a supported but invalid
values or combination of options. Fix that when checking send flags so
it's consistent with the rest.
