There are two directories, 'block' and 'char', + beneath /sys/dev containing symbolic links with names of + the form "<major>:<minor>". These links point to the + corresponding sysfs path for the given device. + + Example: + $ readlink /sys/dev/block/8:32 + ../../block/sdc + + Entries in /sys/dev/char and /sys/dev/block will be + dynamically created and destroyed as devices enter and + leave the system. + +Users: mdadm <linux-raid@vger.kernel.org> |
