Hmmm... there is no filename.c in the kernel... did you mean filemap.c?
I don't see a BUG() call at line 839 in there. A kdb backtrace would be
best if you can reproduce this.
As to the signed thing, I'll tweak growfs so that it report errors.
The kernel interface uses an unsigned value, and the kernel code does
attempt to read at the end of the new size, before proceeding with the
grow operation - in a quick test I just did this seems to be working as
expected; doesn't allow me to grow a "negative" amount (i.e. to a large
offset), just gives a syslog error.
cheers.
