Subject: [PATCH 5/8] btrfs: Increment device corruption error in case of checksum error
Date: Thu, 2 Jul 2020 15:23:32 +0300 [thread overview]
Message-ID: <20200702122335.9117-6-nborisov@suse.com> (raw)
In-Reply-To: <20200702122335.9117-1-nborisov@suse.com>
Now that btrfs_io_bio have access to btrfs_device we can safely
increment the device corruption counter on error. There is one notable
exception - repair bios for raid. Since those don't go through the
normal submit_stripe_bio callpath but through raid56_parity_recover thus
repair bios won't have their device set.
