nilfs2: fix misuse of a semaphore in sysfs code Variables ns_seg_seq, ns_segnum, ns_nextnum, ns_pseg_offset, ns_cno, ns_ctime, ns_nongc_ctime, and ns_ndirtyblks, are protected by ns_segctor_sem, but ns_sem is wrongly used by the nilfs sysfs code when reading these variables. This fixes the misuse and clarifies which semaphore protects them in the comment of the_nilfs struct.
