From 8a2cbe2c6deb93ccfed58fd755c886fce16586a3 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sun, 29 Nov 2009 01:24:06 -0500 Subject: [PATCH] e2fsck: Try to update on-disk bitmap in e2fsck_get_alloc_block() callback The e2fsck_get_alloc_block() callback is used so that if the ext2fs library needs to allocate blocks internally (most notably by the extents functions), e2fsck's internal block usage map is consulted since it is the only thing that can be trusted during a large part of e2fsck's operation. Change it to update the on-disk bitmap if it is loaded. This reduces the number of spurious differences found in pass #5.
