Subject: [PATCH 1/1] Create libeclone.a
The user-api to the eclone() system call is architecture dependent.
Besides checkpoint/restart code, this api could be used by eclone() test
cases (see cr-tests.git tree) and possibly other users of eclone().
To avoid duplication of the arch dependent code, move the api into
libeclone.a (as suggested by Serge Hallyn).
Changelog[v2]:
- Include genstack.o in libeclone.a
Signed-off-by: Sukadev Bhattiprolu <sukadev-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>
Acked-by: Serge Hallyn <serue-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>
