cluster/ec: Allow parallel writes in EC if possible
Problem: Ec at the moment sends one modification fop after another, so if some of the disks become slow, for a while then the wait time for the writes that are waiting in the queue becomes really bad. Fix: Allow parallel writes when possible. For this we need to make 3 changes. 1) Each fop now has range parameters they will be updating. 2) Xattrop is changed to handle parallel xattrop requests where some would be modifying just dirty xattr. 3) Fops that refer to size now take locks and update the locks. Fixes #251 Change-Id: Ibc3c15372f91bbd6fb617f0d99399b3149fa64b2 Signed-off-by: Pranith Kumar K <>
