[ Upstream commit 9272cba0ded71b5a2084da3004ec7806b8cb7fd2 ]
QP table handling is synchronized with destroy QP and Async event from the HW. The same needs to be synchronized during create_qp also. Use the same lock in create_qp also.
Fixes: 76d3ddff7153 ("RDMA/bnxt_re: synchronize the qp-handle table array") Fixes: f218d67ef004 ("RDMA/bnxt_re: Allow posting when QPs are in error") Fixes: 84cf229f4001 ("RDMA/bnxt_re: Fix the qp table indexing") Signed-off-by: Selvin Xavier selvin.xavier@broadcom.com Link: https://patch.msgid.link/20241217102649.1377704-6-kalesh-anakkur.purayil@bro...
