From: Philipp Reisner Date: Tue, 31 May 2011 11:07:24 +0000 (+0200) Subject: drbd: Fixes from the 8.3 development branch X-Git-Tag: v3.8-rc1~78^2~18^2~180 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d942ae44537669418a7cbfd916531d30513dbca8;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git drbd: Fixes from the 8.3 development branch * commit 'ae57a0a': drbd: Only print sanitize state's warnings, if the state change happens drbd: we should write meta data updates with FLUSH FUA drbd: fix limit define, we support 1 PiByte now drbd: fix log message argument order drbd: Typo in user-visible message. drbd: Make "(rcv|snd)buf-size" and "ping-timeout" available for the proxy, too. drbd: Allow keywords to be used in multiple config sections. drbd: fix typos in comments.
