Subject: [PATCH 414/449] cluster-syncop: avoid duplicate unlock of
|
|
inodelk/entrylk
|
|
|
|
When using ec, there are many spam messages in brick and client
|
|
logs files.
|
|
|
|
When shd does entry heal, it takes lock on a directory using
|
|
cluster_tiebreaker_inodelk(). If it does not get lock on all
|
|
the bricks because other clients has got lock on some bricks,
|
|
it will unlock the locks on those bricks which it got and then
|
|
will try blocking locks (If any one of the previous was successful).
|
|
|
|
The problem come here. In case we do not get locks on all the
|
|
required bricks, we are sending unlock request twice on those
|
|
bricks where we got the locks.
|
|
