src/sys/fs/cd9660: cd9660_vfsops.c
Log Message:
Apply a similar fix for mount function from ffs_vfsops.c rev 1.186:
Change cd9660_mount, in MNT_UPDATE case, to check dev_t's for equality
instead of just vnode pointers. Fixes erroneous "Invalid argument"
errors from mount(8) with -u against cd9660 root in the presence of
mfs or tmpfs /dev prepared after initial mountroot.
Tested on QEMU running cobalt Restore CD.
