The two Fixes tags are for the two stable branches: - a4983e89e3b1 is the 6.1.y backport - 32bad10de347 is the 6.6.y backport Both backports changed this allocation from GFP_KERNEL_ACCOUNT back to GFP_KERNEL, which introduced the regression. The accounting was correct before these commits. I used one Fixes tag for each target tree. I am not sure what the usual preference is here: one common patch with both Fixes tags, or separate patches for each tree. Which do you prefer? Thanks, Karl
