From: Theodore Ts'o Date: Sat, 8 Mar 2014 23:13:52 +0000 (-0500) Subject: jbd2: don't unplug after writing revoke records X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=df3c1e9a05ff25aca9f54a6c08b77003e2e32bf1;p=linux-beck.git jbd2: don't unplug after writing revoke records During commit process, keep the block device plugged after we are done writing the revoke records, until we are finished writing the rest of the commit records in the journal. This will allow most of the journal blocks to be written in a single I/O operation, instead of separating the the revoke blocks from the rest of the journal blocks.
