Greetings, Does anyone know the most recent kernel (RHEL/CentOS) that can be successfully patched and compiled against the current Lustre 1.8 git source tree? I attempted 2.6.18-308.1.1 but there are several patches that fail. Quilt would not make it past the third patch in the series file.

I applied that patch at 9AM this morning. Several hunks failed and then I noticed that the LU-1052 patch is literally morphing as the morning progresses. There is a difference between living on the bleeding edge and standing in a field watching the razor's edge coming at you... :) On Thu, Mar

Heh. Nice imagery Jeff. Yes, this patch is still under active development and also note that it will not be able to complete autotest until we switch it to use RHEL5.8 by default (hopefully soon, but this had been on hold until we saw whether we needed RC3 for 2.2). So, if you are willing to
