__submit_merged_bio f2fs_write_end_io f2fs_write_end_io
wait_io = X wait_io = x
complete(X) complete(X)
wait_io = NULL
wait_for_completion()
free(X)
spin_lock(X)
kernel panic
In order to avoid this, this patch removes the wait_io facility.
Instead, we can use wait_on_all_pages_writeback(sbi) to wait for end_ios.
