As indicated in this thread, there is an overflow problem in ffs_dirpref
for large filesystems. The symptom is an integer divide-by-zero exception
at ffs_dirpref+0x1e8 (at least on a recent -CURRENT). This bug has been
around for a year plus. Who else has seen this, and is anyone working on it
before I do? It looks like it would reliably happen on any large FS for
which you increase the average file size.
I'm going to go through and change some types to int64_t and see if I can
get this to stop panicking on my 1TB filesystem. Any advice that would lead
to less hassle would be much appreciated.
