I figured I''d take a swing at 1.6b7 on 2.6.18.6 vanilla prior to the release of a better patchset, to get a handle on what other stuff might have cropped up. I''ve slogged my way through some less important bugs, but now have run into a failure trying to compile lustre/obdfilter/filter_io_26.c. It appears that in 2.6.18.6 the PF_SYNCWRITE flag is no longer defined. Am I missing something? Is anybody else running 1.6b7 on a 2.6.18-ish kernel?
