From 13ee854e7c04236a47a5beaacdcf51eb0bc7a8fa Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Wed, 5 Feb 2025 11:36:46 +0000 Subject: io_uring/kbuf: remove legacy kbuf caching Remove all struct io_buffer caches. It makes it a fair bit simpler. Apart from from killing a bunch of lines and juggling between lists, __io_put_kbuf_list() doesn't need ->completion_lock locking now.
