--------------------------------
This issue as follows When do IO fault injection test: Quota error (device dm-3): find_block_dqentry: Quota for id 101 referenced but not present Quota error (device dm-3): qtree_read_dquot: Can't read quota structure for id 101 Quota error (device dm-3): do_check_range: Getting block 2021161007 out of range 1-186 Quota error (device dm-3): qtree_read_dquot: Can't read quota structure for id 661
Now, ext4_write_dquot()/ext4_acquire_dquot()/ext4_release_dquot() may commit inconsistent quota data even if process failed. This may lead to filesystem corruption. To ensure filesystem consistent when errors=remount-ro there is need to call ext4_handle_error() to abort journal.
