fs: f2fs: Remove unnecessary checks of SM_I(sbi) in update_general_status() (280fd422) · Commits · 戴 / test

In fill_super() and put_super(), f2fs_destroy_stats() is called in prior to f2fs_destroy_segment_manager(), so if current sbi can still be visited in global stat list, SM_I(sbi) should be released yet. For this reason, SM_I(sbi) does not need to be checked in update_general_status(). Thank Chao Yu for advice. Signed-off-by:
