Modified files:
dlm-kernel/src : lkb.c
Log message:
Don't create lkids of 0. When the lkid counter for bucket 0 of the
hash table rolls over (it's uint16), we'd get a lkid of zero and
assign it to the new lkb. lock_dlm would be confused by a zero lkid
and use some other, incorrect value as the lkid which would lead to
a dlm error which would lead to a lock_dlm/gfs panic.
this should fix bz 199673
it may also fix bz 172944
