Subject: [PATCH] Allow usage of getrpcbynumber() when getrpcbynumber_r() is
|
|
not available
|
|
|
|
getrpcbynumber_r() is not implemented by libtirpc at the moment, only
|
|
the non-reentrant getrpcbynumber() is available. Since nfs-utils seems
|
|
to only be using getrpcbynumber_r() is a non multithreaded context,
|
|
using getrpcbynumber() should work just as well.
|
|
|
|
We also take this opportunity to adjust the autoconf checks to verify
|
|
whether any of getrpcbynumber() or getrpcbynumber_r() is available,
|
|
and error out if none of them is available.
