Message-ID: <20101220133913.7994.qmail@sourceware.org> (raw)
CVSROOT: /cvs/lvm2
Module name: LVM2
Changes by: zkabelac at sourceware.org 2010-12-20 13:39:13
Modified files:
libdm : libdevmapper.h
Log message:
Use const char* for offset calculation
As 'const' types are also passed to macro dm_list_struct_base -
keep offset calculation with const char pointers.
Fixes several gcc constness warnings.
