+ * add a GROUP_BY_SERIAL flag. This should be useful for
+ controlers that activate they spare paths on simple IO
+ submition with a penalty. The StorageWorks HW defaults to
+ this mode, even if the MULTIBUS mode is OK.
+ * remove unused sg_err.c
+ * big restructuring : split devinfo.c from main.c. Export :
+ * void basename (char *, char *);
+ * int get_serial (int, char *);
+ * int get_lun_strings (char *, char *, char *, char *);
+ * int get_evpd_wwid(char *, char *);
+ * long get_disk_size (char *);
+ * stop passing struct env as param
+ * add devmap_name proggy for udev to name devmaps as per their
+ internal DM name and not only by their sysfs enum name (dm-*)
+ The corresponding udev.rules line is :
+ KERNEL="dm-[0-9]*", PROGRAM="/sbin/devmap_name %M %m", NAME="%k", SYMLINK="%c"
