Description:
Linux Kernel Device Mapper event support library
The Linux Kernel Device Mapper is the LVM (Linux Logical Volume Management) Team's implementation of a minimalistic kernel-space driver that handles volume management, while keeping knowledge of the underlying device layout in user-space. This makes it useful for not only LVM, but software raid, and other drivers that create "virtual" block devices. . This package contains the userspace library to help with event monitoring for devmapper devices, in conjunction with the dmevent daemon.
