Subject: drbd: increase module count on /proc/drbd access
X-Git-Tag: v2.6.39-rc1~37^2~88

drbd: increase module count on /proc/drbd access

If someone holds /proc/drbd open, previously rmmod would
"succeed" in starting the unload, but then block on remove_proc_entry,
leading to a situation where the lsmod does not show drbd anymore,
but /proc/drbd being still there (but no longer accessible).

I'd rather have rmmod fail up front in this case.
