If I could merge it in, that it would be better, since the gigantic patch is still applying to the 188.8.131.52 source. linux-2.6# git merge linux-bcache fatal: 'linux-bcache' does not point to a commit
Err, that should be whatever the bcache branch was named, probably just bcache.

Is there a 18.104.22.168 patch available? If not, can I make one? Looking at this helpful human's post, it looks fairly straightforward: http://comments.gmane.org/gmane.linux.kernel.bcache.devel/24 I checked out both trees, then switched to my branch: git checkout -b 22.214.171.124 Then created the patch: git diff linux-2.6 linux-bcache>patchYou probably want something like git diff v2.6.34 linux-bcache> patch Really you should just be able to do a git merge linux-bcache from the 2.6.34-stable branch though...However, this resulted in a 236MB patch file, which is several orders of magnitude bigger than any other patch I have ever used. Assuming this is even the right way to do it, do I just install it by moving it into my running kernel's source and doing a patch -p0 patch ? Slightly un-related question: I want to use this as a cache for two sw raid6 arrays. The raid devices have a bunch of logical volumes carved out of them and those LVs are presented to LIO and served out as iSCSI LUNs. Will bcache serve as a write cache for these devices? My read performance is great, but my random write performance, or write performance in general, really sucks hard.Yeah, writeback caching has been implemented for quite awhile now, just have to flip it on :) echo 1> /sys/block/bcache0/bcache/writeback
