Feature #310942, revision 1
Title: include BCache (cache on SSD) in kernel

openSUSE-11.4: Unconfirmed
Priority
Requester: Desirable

Requested by: Vadims Korsaks (truckk)
Partner organization: openSUSE.org

Description:
Bcache is a patch to use SSDs to transparently cache arbitrary block devices.
Its main claim to fame is that it's designed for the performance
characteristics of SSDs - it avoids random writes and extraneous IO at all
costs, instead allocating buckets sized to your erase blocks and filling them
up seqentially. It uses a hybrid btree/log, instead of a hash table as some
other caches.

Business case (Partner benefit):
openSUSE.org: SSD devices can help improve rotation disks performance, this
will give better overal performance and allow to use big rotation disks
capacity.
