Subject: [PATCH] libmultipath: deal with dynamic PTHREAD_STACK_MIN
|
|
|
|
Starting in glibc-2.34 (commit 5d98a7da), PTHREAD_STACK_MIN is defined
|
|
as sysconf(_SC_THREAD_STACK_MIN) if _GNU_SOURCE is defined. sysconf()
|
|
returns a long and can, at least in theory, return -1. This change
|
|
causes compilation to fail in setup_thread_attr() due to a comparision
|
|
with different signedness, since stacksize is a size_t.
