| H A D | io-wq.c | 1bbadf95 Tue Jun 04 07:12:43 CDT 2024 Su Hui <suhui@nfschina.com> io_uring/io-wq: avoid garbage value of 'match' in io_wq_enqueue()
[ Upstream commit 91215f70ea8541e9011c0b48f8b59b9e0ce6953b ]
Clang static checker (scan-build) warning:
o_uring/io-wq.c:line 1051, column 3
The expression is an uninitialized value. The computed value will
also be garbage.
'match.nr_pending' is used in io_acct_cancel_pending_work(), but it is
not fully initialized. Change the order of assignment for 'match' to fix
this problem.
Fixes: 42abc95f05bf ("io-wq: decouple work_list protection from the big wqe->lock")
