PROBLEM: multiple mount of devices possible 2.4.0-test1 - 2.4.0-test13-pre4
1. multiple mount of devices possible 2.4.0-test1 - 2.4.0-test13-pre4 2. its still possible to mount devices several times. IMHO it shouldnt be possible like 2.2.18 with umount in /proc/mounts is still the real information, in /etc/mtab all corresponding mountpoints are deleted. 3. kernel, filesystem, mount 4.

PROBLEM: test13-pre3, e2fs corruption
1. test13-pre3, e2fs corruption 2. running my box 4h 30min i wanted edit some files, the filenames were wrong and other files didnt have the correct data. i unmounted the drive with the data and a e2fsck said wrong group names...bad superblock... after reboot without check or repair on 2.2.18 no problems reported and all my data are correct. some days before i tried mount my atapi-cdrom and my box hangs completly with test12 or test13-pre1, couldnt reproduce it yet. (no overclocking) 3. e2fs filesystem 4.
