Series ext4: fix inconsistency since reading old metadata from disk | expand

Commit Message

Zhang Yi June 17, 2020, 11:59 a.m. UTC 
After we add ext4_end_buffer_async_write() callback into block layer to
detect metadata buffer's async write error in the background, we can
remove the partial fix for filesystem inconsistency problem caused by
reading old data from disk in commit <9c83a923c67d> "ext4: don't read
inode block if the buffer has a write error".
