[linux-lvm] LVM and sw RAID1

[Luca Berra]

good it seems you found the first bug in lvm_dir_cache

the second bug is in a function called something like 
pv_check_all_pv it tries to remove all block devices that are part
of an md device, finds none and removes the md device.

obviously this check is not needed unless you have a raid partition
of type 0x8e, or you use full disks.

good luck

P.S. i noticed the result of this routines varies depending with
system configuration, at one particular point pv_check_all_pv did
segfault on me, i removed a disk an it did work :(

i suggest someone reviews that code.
