ext4: forbid commit inconsistent quota data when errors=remount-ro
[ Upstream commit d8b945fa475f13d787df00c26a6dc45a3e2e1d1d ]
There's 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.
