From: Dave Chinner <dchinner@xxxxxxxxxx> Source kernel commit: a6a65fef5ef8d0a6a0ce514eb66b2f3dfa777b48 We don't need to look at the xfs_mount and superblock every time we need to do an iclog roundoff calculation. The property is fixed for the life of the log, so store the roundoff in the log at mount time and use that everywhere.
