Hi, Yuan, > After commit 0e96454ca26c("dmaengine: idxd: remove fault processing code"), > no one use struct idxd_fault, so remove it. How about this commit message? Since fault processing code has been removed, struct idxd_fault is not used any more and can be removed as well. Fixes: commit 0e96454ca26c ("dmaengine: idxd: remove fault processing code") Thanks. -Fenghua
