drivers/infiniband/sw/rxe/rxe_pool.c:360:21-31: ERROR: function rxe_alloc_nl called on line 385 inside lock on line 384 but uses GFP_KERNEL

 Find functions that refer to GFP_KERNEL but are called with locks held.

Semantic patch information:
 The proposed change of converting the GFP_KERNEL is not necessarily the
 correct one.  It may be desired to unlock the lock, or to not call the
 function under the lock in the first place.
