| | | | | | | | | | | | | | | | | | | | | | | For making mmap cache code reusable from other areas in strace than unwind, mmap cache related code and unwind related code should be separated.

(mmap_cache_invalidate, mmap_cache_delete, mmap_cache_rebuild_if_invalid): New function prototypes. (struct mmap_cache_t, enum mmap_cache_rebuild_result): Move from unwind.c. * syscall.c (syscall_exiting_decode): Replace unwind_cache_invalidate with mmap_cache_invalidate.
