[LTP] [PATCH v1 1/9] Remove libclone dependency from sysvipc
Andrea Cervesato
andrea.cervesato@suse.de
Tue Feb 8 11:09:40 CET 2022
This is the step 1 before rewriting all sysvipc tests using new
LTP API. Substituted ipcns_helper.h with a common.h header for all
tests. The new common.h file includes some helpers functions, as
well as specific clone functionalities.
