locking/refcount: Define constants for saturation and max refcount values

2019-11-25T08:14:13+00:00

The REFCOUNT_FULL implementation uses a different saturation point than the x86 implementation, which means that the shared refcount code in lib/refcount.c (e.g. refcount_dec_not_one()) needs to be aware of the difference. Rather than duplicate the definitions from the lkdtm driver, instead move them into and update all references accordingly.

lkdtm: Relocate code to subdirectory

2018-03-07T03:18:55+00:00

The LKDTM modules keep expanding, and it's getting weird to have each file get a prefix. Instead, move to a subdirectory for cleaner handling. Signed-off-by: Kees Cook Signed-off-by: Greg Kroah-Hartman
