Sowmini Varadhan d4014d8cc6 rds: do not call ->conn_alloc with GFP_KERNEL ... Commit ebeeb1ad9b ("rds: tcp: use rds_destroy_pending() to synchronize netns/module teardown and rds connection/workq management") adds an rcu read critical section to __rd_conn_create. The memory allocations in that critcal section need to use GFP_ATOMIC to avoid sleeping. This patch was verified with syzkaller reproducer.
