Chuck Lever 417efc5202 xprtrdma: Convert send buffer free list to llist ... rpcrdma_buffer_get() and rpcrdma_buffer_put() both take rb_lock to pop/push from the rb_send_bufs free list. Under high I/O concurrency (e.g., nconnect=N with small random writes), this spinlock is contended between the request submission path and the transport completion path. Replace the list_head with an llist_head. The put side uses lockless llist_add(), which is safe for concurrent producers. The get side retains the spinlock to satisfy the llist single-consumer contract portably; submitters continue to serialize there. Completion handlers returning buffers no longer contend on rb_lock, eliminating contention on the return path. rb_lock remains for the MR free list and the tracking lists used during setup and teardown. rb_free_reps already uses llist_head, so the llist idiom is established in this structure. The precedent is the data structure, not the locking: rb_free_reps serializes its single consumer through the re_receiving gate in rpcrdma_post_recvs, whereas rb_send_bufs serializes its consumer with rb_lock. Both satisfy the llist single-consumer contract. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Anna Schumaker <anna.schumaker@hammerspace.com>		2026-06-10 15:47:05 -04:00
