[Libsysio-commit] HEAD: libsysio/src mount.c

[Lee W. <lw...@us...>]

Update of /cvsroot/libsysio/libsysio/src
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv9909

Modified Files:
	mount.c 
Log Message:


Added the tiniest bit of paranoia to _sysio_do_mount. Basically, just want
to make sure we aren't somehow, strangely, mounting on a pnode that
is already mounted on. I can't see how this could happen but I like explicit
failures instead of weird behavior.
