Subject: [PATCH 2/5] ext4: Fix trimmed block count computing
Date: Thu,  1 Mar 2012 11:16:42 +0100	[thread overview]
Message-ID: <1330597005-751-2-git-send-email-lczerner@redhat.com> (raw)
In-Reply-To: <1330597005-751-1-git-send-email-lczerner@redhat.com>

Currently then if there is not enough free block in the block group to
discard (grp->bb_free >= minlen) the 'trimmed' is bumped up anyway with
the number of discarded blocks from the previous block group. Fix this
by bumping up 'trimmed' only if the ext4_trim_all_free() was actually
run.
