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

[jaschut <ja...@us...>]

Update of /cvsroot/libsysio/libsysio/src
In directory sc8-pr-cvs1:/tmp/cvs-serv20287

Modified Files:
	mount.c 
Log Message:
In _sysio_do_mount(), change the inop_getattr() call to
_sysio_p_validate(), since the latter should be checking the inode
mode bits, and is potentially cheaper.
