drbd: check MODULE for THIS_MODULE

2017-11-11T13:34:42Z

commit bc4854bc91c9a7f117437215cd8b16a0a5671d93 upstream. THIS_MODULE is NULL only when drbd is compiled as built-in, so the #ifdef CONFIG_MODULES should be #ifdef MODULE instead. This fixes the warning: drivers/block/drbd/drbd_main.c: In function ‘drbd_buildtag’: drivers/block/drbd/drbd_main.c:4187:24: warning: the comparison will always evaluate as ‘true’ for the address of ‘__this_module’ will never be NULL [-Waddress] Signed-off-by: WANG Cong Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg Signed-off-by: Ben Hutchings

drbd: fix for deadlock when using automatic split-brain-recovery

2013-05-30T13:35:10Z

commit 7c689e63a847316c1b2500f86891b0a574ce7e69 upstream. With an automatic after split-brain recovery policy of "after-sb-1pri call-pri-lost-after-sb", when trying to drbd_set_role() to R_SECONDARY, we run into a deadlock. This was first recognized and supposedly fixed by 2009-06-10 "Fixed a deadlock when using automatic split brain recovery when both nodes are" replacing drbd_set_role() with drbd_change_state() in that code-path, but the first hunk of that patch forgets to remove the drbd_set_role(). We apparently only ever tested the "two primaries" case. Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg Signed-off-by: Jens Axboe Signed-off-by: Ben Hutchings

drbd: add missing part_round_stats to _drbd_start_io_acct

2013-02-06T04:33:56Z

commit 72585d2428fa3a0daab02ebad1f41e5ef517dbaa upstream. Without this, iostat frequently sees bogus svctime and >= 100% "utilization". Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg Signed-off-by: Ben Hutchings
