Subject: [PATCH] libmultipath: fix tur checker timeout issue
|
|
|
|
If the tur checker is run, and the tur_thread has timed out,
|
|
libcheck_check() doesn't actually check if the thread is still running.
|
|
This means that the thread could have already completed successfully,
|
|
but the tur checker would still return PATH_TIMEOUT, instead of the
|
|
value returned by the thread. This patch makes libcheck_check() actually
|
|
check if the thread completed, and if so, it returns the proper value.
|
