cluster/afr: Turn on eager-lock for fd DATA transactions
Problem: With the present implementation, eager-lock is issued for any fd fop. eager-lock is being transferred to metadata transactions. But the lk-owner is set to local->fd address only for DATA transactions, but for METADATA transactions it is frame->root. Because of this unlock on the eager-lock fails and rebalance hangs. Fix: Enable eager-lock for fd DATA transactions Change-Id: If30df7486a0b2f5e4150d3259d1261f81473ce8a BUG: 916226 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/4588 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
