Subject: io_uring: remove 'issue_flags' argument for io_req_set_rsrc_node()
X-Git-Tag: v6.13-rc1~210^2~58
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1caa00d6b61651e04c04c2b50b3e149f24c6764d;p=thirdparty%2Fkernel%2Flinux.git

io_uring: remove 'issue_flags' argument for io_req_set_rsrc_node()

All callers already hold the ring lock and hence are passing '0',
remove the argument and the conditional locking that it controlled.
