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 initialized. Change the order of assignment for 'match' to fix this problem.
