No, that printk() is fine, the format string says "%llu" so the cast is
unsigned long long.
Besides which, line 534 in the Debian 2.6.32 kernel I am using is this
one:
J_ASSERT(commit_transaction->t_nr_buffers <=
commit_transaction->t_outstanding_credits);
If somebody can tell me what information would help to debug this I'd be
more than happy to throw a whole bunch of debug printks under that error
condition and try to trigger the crash with that.
Alternatively I could remove that J_ASSERT() and instead add some debug
further down around the "commit_transaction->t_outstanding_credits--;"
to try to see exactly what IO it's handling when it runs out of credits.
Any ideas?
