This subsystem is a spin-off of the mmap_cache subsystem. The mmap_cache subsystem had two features: (1) tracking the change of memory mapping, and (2) maintaining the cache of memory mapping. mmap_notify is a subsystem specialized to provide feature (2). unwind-libdw itself has the feature (1). It needs only (2). * mmap_notify.h: New file. * mmap_notify.c: Likewise. * Makefile.am (strace_SOURCES): Add them. Signed-off-by: Masatake YAMATO <yamato@redhat.com>
