In update_general_status(), there are two if statements to check whether SM_I(sbi) is NULL: LINE 70: if (SM_I(sbi) && SM_I(sbi)->fcc_info) LINE 78: if (SM_I(sbi) && SM_I(sbi)->dcc_info)
When SM_I(sbi) is NULL, it is used at some places, such as: LINE 88: reserved_segments(sbi) return SM_I(sbi)->reserved_segments; LINE 89: overprovision_segments(sbi) return SM_I(sbi)->ovp_segments; LINE 112: MAIN_SEGS(sbi) (SM_I(sbi)->main_segments) Thus, possible null-pointer dereferences may occur. These bugs are found by a static analysis tool STCheck written by us. I do not know how to correctly fix these bugs, so I only report them. Best wishes, Jia-Ju Bai
