[f2fs-dev] [PATCH v3 2/2] f2fs: use more generic f2fs_stop_checkpoint()

Chao Yu via Linux-f2fs-devel

Let's use more generic f2fs_stop_checkpoint() instead of
f2fs_handle_critical_error() to handle critical error in f2fs.

v3:
This patch depends on "f2fs: call f2fs_handle_critical_error() to set
cp_error flag", so send it as a patchset.
