| Subject: [PATCH] io_uring: Replace pthread_self with s->tid |
| |
| __init_rand64 takes 64bit value and srand48 takes unsigned 32bit value, |
| pthread_t is opaque type and some libcs ( e.g. musl ) do not define them |
| in plain old data types and ends up with errors |
| |
| | t/io_uring.c:809:32: error: incompatible pointer to integer conversion passing 'pthread_t' (aka 'struct __pthread *') to parameter of type 'uint64_t' (aka 'unsigned long') [-Wint-conver |
| sion] |
| | __init_rand64(&s->rand_state, pthread_self()); |
| | ^~~~~~~~~~~~~~ |
