Michal Hocko 6ccaf3e2f3 jbd2: revert must-not-fail allocation loops back to GFP_NOFAIL ... This basically reverts 47def82672 (jbd2: Remove __GFP_NOFAIL from jbd2 layer). The deprecation of __GFP_NOFAIL was a bad choice because it led to open coding the endless loop around the allocator rather than removing the dependency on the non failing allocation. So the deprecation was a clear failure and the reality tells us that __GFP_NOFAIL is not even close to go away. It is still true that __GFP_NOFAIL allocations are generally discouraged and new uses should be evaluated and an alternative (pre-allocations or reservations) should be considered but it doesn't make any sense to lie the allocator about the requirements. Allocator can take steps to help making a progress if it knows the requirements.
