Changes by: wysochanski@sourceware.org 2009-07-26 14:36:52
Modified files:
liblvm : .exported_symbols lvm.h lvm_lv.c
Log message:
Add lvm_vg_remove_lv liblvm function.
Add a very simple version of lvm_vg_remove_lv.
Since we currently can only create linear LVs, this simple remove function
is adequate. We must refactor lvremove_single a bit.
