This patch adds individual resource tracking for e2fsck's pass1[b-d] phase. On ext2, time tracking for pass1 includes both error detection and specific type of fs fix-up phase (e.g. block referenced by multiple inodes). The multi-reference fix-up phase some time take significant amount of time to complete. We would like to track time spent in sub component of pass1 by having a finer granularity during pass1b through pass1d phase.
