Subject: [PATCH 2/5] xfs: pass current lsn to log recovery buffer validation
Date: Thu, 11 Aug 2016 13:11:04 -0400	[thread overview]
Message-ID: <1470935467-52772-3-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1470935467-52772-1-git-send-email-bfoster@redhat.com>

The current LSN must be available to the buffer validation function to
provide the ability to update the metadata LSN of the buffer. Pass the
current_lsn value down to xlog_recover_validate_buf_type() in
preparation.
