Created attachment 323931 [details] dlm kernel patch Memory allocations in the dlm should use GFP_NOFS to avoid looping back into gfs to free memory, which may require dlm operations, causing deadlock. Most dlm allocations already use GFP_NOFS (usually via ls_allocation), but this patch fixes up some that have been missed. AFAIK, no one has actually observed deadlock between dlm and gfs due to any of the allocations changed by this patch. But apparently the patch still has an effect somehow, in delaying the onset of gfs2 bug 460218.
