Subject: What's in linux-2.6-block.git for 2.6.27
Hi,
So this time it's a little beyond just block stuff, since the
generic-ipi branch is included (in preparation for block parts actually
using that code).
- xen block bits
- Write starvation fix for 'AS', a very long standing bug
- CFQ using the message trace for debugging.
- Ability to inject messages into the blktrace stream from user space,
which helps annotate a longer running trace where you make changes
meanwhile.
- Finally kill off request_queue_t typedef.
- The data integrity block parts.
- Export of the disk read-only attribute in sysfs
- The generic-ipi smp helpers and a slew of arch conversions.
All of the above can be viewed/tested in the for-next branch, which is
what Stephen is pulling as well. For manual code browsing, go to gitweb
here:
http://git.kernel.dk/?p=linux-2.6-block.git;a=shortlog;h=refs/heads/for-next
or pull
git://git.kernel.dk/linux-2.6-block.git for-next
if you want to get at the source. Changelog below.
