Subject: nilfs2: fix incorrect KERN_CRIT messages in case of write failures
X-Git-Tag: firefly_0821_release~13436^2~2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=4a52df779700080de4afb0436d9dd9188514a69b;p=firefly-linux-kernel-4.4.55.git

nilfs2: fix incorrect KERN_CRIT messages in case of write failures

In case of write-failure retries, the following KERN_CRIT level
messages are mistakenly output by nilfs_dat_commit_start() function:

nilfs_dat_commit_start: vbn = 408463, start = 12506, end = 18446744073709551615, pbn = 530210
nilfs_dat_commit_start: vbn = 408515, start = 12506, end = 18446744073709551615, pbn = 530211
nilfs_dat_commit_start: vbn = 408464, start = 12506, end = 18446744073709551615, pbn = 530212
...

This suppresses these messages.
