Same seems to be > the case for lkml. I am wondering what happened to rest of the patches. Same here. But, the rest of the patches showed up much later. In any case you can access the fullset from here http://git.kernel.org/?p=linux/kernel/git/wfg/linux.git;a=shortlog;h=refs/heads/buffered-write-io-controller > Will understand the patches better once I have the full set. >
