From df3c1e9a05ff25aca9f54a6c08b77003e2e32bf1 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sat, 8 Mar 2014 18:13:52 -0500 Subject: 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.
