Subject: [PATCH 08/32] e2fsck: print runs of duplicate blocks instead of all of them
Date: Sat, 01 Mar 2014 23:17:30 -0800 [thread overview]
Message-ID: <20140302071730.28217.49955.stgit@birch.djwong.org> (raw)
In-Reply-To: <20140302071639.28217.57302.stgit@birch.djwong.org>
When pass1 finds blocks that are mapped to multiple files, it will
print every duplicated block. If there are long sequences of
duplicate blocks (e.g. the e_pblk field is wrong in an extent), this
can cause a gigantic flood of output when a range could convey the
same information. Therefore, teach pass1b to print ranges when
possible.
