H A D | relocation.c | 726a3421 Mon Feb 17 00:16:52 CST 2020 Qu Wenruo <wqu@suse.com> btrfs: relocation: add error injection points for cancelling balance
Introduce a new error injection point, should_cancel_balance().
It's just a wrapper of atomic_read(&fs_info->balance_cancel_req), but allows us to override the return value.
Currently there are only one locations using this function:
- btrfs_balance() It checks cancel before each block group.
There are other locations checking fs_info->balance_cancel_req, but they are not used as an indicator to exit, so there is no need to use the wrapper.
But there will be more locations coming, and some locations can cause kernel panic if not handled properly. So introduce this error injection to provide better test interface.
