RDMA/usnic: Lock VF with mutex instead of spinlock
Usnic VF doesn't need lock in atomic context to create QPs, so it is safe to use mutex instead of spinlock. Such change fixes the following smatch error. Smatch static checker warning: lib/kobject.c:289 kobject_set_name_vargs() warn: sleeping in atomic context Fixes: 514aee66 ("RDMA: Globally allocate and release QP memory") Link: https://lore.kernel.org/r/2a0e295786c127e518ebee8bb7cafcb819a625f6.1631520231.git.leonro@nvidia.com Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Leon Romanovsky <leonro@nvidia.com> Reviewed-by: Håkon Bugge <haakon.bugge@oracle.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
