Bryn M. Reeves	1134de3c89	libdm: fix FILE leak in _program_id_from_proc() (Coverity) ... Make sure comm is closed in the error path of _program_id_from_proc(). libdm/libdm-stats.c: 98 in dm_stats_create() - Variable "comm" going out of scope leaks the storage it points to.	2015-08-10 20:20:26 +01:00
Bryn M. Reeves	d62a8d2f15	dmstats: add libdm-stats library and 'dmsetup stats' command ... Add the libdm-stats module to libdm: this implements a simple interface for creating, managing and interrogating I/O statistics regions and areas on device-mapper devices. The library interface is documented in libdevmapper.h and provides a 'dm_stats' handle that is used to perform statistics operations and obtain data. Public methods are provided to create and destroy handles and to list, create, and destroy statistics regions as well as to obtain and parse counter data and calculate rate-based metrics. This commit also adds a 'dmsetup stats' (aka 'dmstats') command with 'clear', 'create', 'delete', 'list', 'print', and 'report' sub-commands. See the library documentation and the dmstats.8 manual page for detailed API and command descriptions.	2015-08-09 14:37:58 +01:00
