Subject: [PATCH 587/587] extras: Turn eager-lock off for gluster-block
Backport of https://review.gluster.org/17954
With the current implementation of eager-lock FINODELK is taking so much
time that cassandra workload times out and errors out. AFR eager-locking
needs to be changed similar to EC eager-locking to make things work
as expected. In the interim, it is better to turn it off
This is how the profile looks if eager-lock is turned on:
0.35 628.26 us 64.00 us 129882.00 us 42278 FXATTROP
17.45 16500.54 us 212.00 us 375829.00 us 79568 WRITE
81.76 209862.12 us 15.00 us 1992486.00 us 29318 FINODELK
This is how profile looks if eager-lock is turned off:
1.87 283.71 us 65.00 us 298970.00 us 68346 FXATTROP
6.33 199.04 us 13.00 us 373428.00 us 330524 FINODELK
