Subject: [PATCH] Btrfs: don't flush delalloc arbitrarily
Date: Fri, 15 Jul 2011 12:01:03 -0400 [thread overview]
Message-ID: <1310745663-17155-1-git-send-email-josef@redhat.com> (raw)
Kill the check to see if we have 512mb of reserved space in delalloc and
shrink_delalloc if we do. This causes unexpected latencies and we have other
logic to see if we need to throttle. Thanks,
Signed-off-by: Josef Bacik <josef@redhat.com>
