[PATCH v3 7/7] net/hinic: fix mutexes for multi-process

[Stephen Hemminger]

The hinic driver supports secondary processes. Mutexes in structures
allocated in shared memory must be initialized with
PTHREAD_PROCESS_SHARED. All callers of hinic_mutex_init() pass NULL
as the attribute argument, so route it through the EAL helper and
drop the unused parameter handling.

Bugzilla ID: 662
Fixes: ae865766b334 ("net/hinic: replace spinlock with mutex")
