drbd: reset congestion information before reporting it in /proc/drbd

2012-07-24T12:07:48+00:00

We cache the congestion status in mdev->congestion_reason whenever
drbd_congested() was called.
Reset this cached info before reporting it when reading /proc/drbd.

drbd: cosmetic: fix accidental division instead of modulo when pretty printing

2012-05-09T08:01:39+00:00

For large resync rates, seq_printf_with_thousands_grouping()
accidentally only produced Y,000,00Y, instead of the real numbers.

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.
