Subject: [Drbd-dev] request for review - DRBD multi volume support for 3.2
Date: Mon, 8 Aug 2011 15:57:47 +0200 [thread overview]
Message-ID: <201108081557.48504.philipp.reisner@linbit.com> (raw)
This is a request for review of drbd-8.4. I intend to send a pull request
to Jens early next week, for his for-3.2/drivers branch.
I want to point out the idr_for_each_entry() macro, added to
include/linux/idr.h. Though we use this macro extensively in the new DRBD
code, it is not DRBD specific. I intend to leave it in this patch series, as
the following patches depend on it.
The most noticeable change is the support for multiple replicated volumes in
a single DRBD connection. Write-ordering is obeyed among all writes in all
volumes in a single connection. This feature is really important for users
who DRBD for mirroring over longer distances. (Protocol A).
The following changes since commit f963d270cb7bbb8eeb57901d02b22a493e664fd2:
cciss: add transport mode attribute to sys (2011-08-08 11:40:17 +0200)
