1autofs-5.0.7 - use numeric protocol ids instead of protoent structs
2
3From: Leonardo Chiquitto <leonardo.lists@gmail.com>
4
5The function getprotobyname() is not reentrant, so we can't call
6it simultaneously from multiple threads. Instead of switching to
7the reentrant version which adds more complexity to the code,
8lets use numeric protocol IDs instead of protoent structures.
