Subject[PATCH 09/14] staging/lustre/ptlrpc: Suppress error for flock requests
Date
From: Patrick Farrell <paf@cray.com>

-EAGAIN is a normal return when requesting POSIX flocks.
We can't recognize exactly that case here, but it's the
only case that should result in -EAGAIN on LDLM_ENQUEUE, so
don't print to console in that case.
