Subject: [PATCH] Btrfs: fix ordered extent check in btrfs_punch_hole
Date: Tue, 19 Nov 2013 16:19:24 +0000 [thread overview]
Message-ID: <1384877964-8286-1-git-send-email-fdmanana@gmail.com> (raw)
If the ordered extent's last byte was 1 less than our region's
start byte, we would unnecessarily wait for the completion of
that ordered extent, because it doesn't intersect our target
range.
