Subject: [PATCH] bnx2fc: Fix locking requirements in bnx2fc_init_tgt
Date: Tue, 5 Apr 2016 10:36:46 -0400 [thread overview]
Message-ID: <1459867006-19605-1-git-send-email-bastienphilbert@gmail.com> (raw)
This fixes the locking around the call to bnx2fc_alloc_id to comply
with the comments about this particular function's definition about
requiring the need to hold the hba mutex before and after calling
it.
