drbd: increase module count on /proc/drbd access

2011-03-10T10:35:11+00:00

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.

drbd: restore compatibility with 32bit kernels

2011-03-10T10:19:13+00:00

With commit
drbd: further converge progress display of resync and online-verify
accidentally an u64/u64 div was introduced, causing an unresolvable
symbol __udivdi3 to be reference. Actually for that division, 32bit are
still suficient for now, so we can revert to unsigned long instead.

drbd: further converge progress display of resync and online-verify

2011-03-10T10:19:06+00:00

Show progressbar and ETA always, with proc_details >= 1 also show the
current sector position for both resync and online-verify on both nodes.

drbd: fix potential wrap of 32bit oos:%lu display in /proc/drbd

2011-03-10T10:19:04+00:00

When converting bits (4k resolution, still) to kB, we shift left.  If it
was a large number of bits on a 32bit box (>= 4 TiB storage), we may
wrap the 32bit unsigned long base type, resulting in incorrect display.

drbd: improve online-verify progress tracking

2011-03-10T10:18:51+00:00

For a partial (resumed) online-verify, initialize rs_total not to total
bits, but to number of bits to check in this run, to match the meaning
rs_total has for actual resync.

drbd: cleanup: change "<= 0" to "== 0"

2010-10-14T17:17:23+00:00

dt is unsigned so it's never less than zero.  We are calculating the
elapsed time, and that's never less than zero (unless there is a bug or
we invent time travel).  The comparison here is just to guard against
divide by zero bugs.
