From 3af3d772f7216cf23081bb4176e86f1219d32ebc Mon Sep 17 00:00:00 2001 From: "zhangyi (F)" Date: Sat, 13 Mar 2021 11:01:45 +0800 Subject: block_dump: remove block_dump feature We have already delete block_dump feature in mark_inode_dirty() because it can be replaced by tracepoints, now we also remove the part in submit_bio() for the same reason. The part of block dump feature in submit_bio() dump the write process, write region and sectors on the target disk into kernel message. it can be replaced by block_bio_queue tracepoint in submit_bio_checks(), so we do not need block_dump anymore, remove the whole block_dump feature.
