Browse Source 
* unwind.c (init_unwind_addr_space): Rename to unwind_init.
(init_libunwind_ui): Rename to unwind_tcb_init.
(free_libunwind_ui): Rename to unwind_tcb_fin.
(delete_mmap_cache): Rename to unwind_cache_invalidate.
(print_stacktrace): Rename to unwind_print_stacktrace.
* defs.h: Update prototypes.
* mem.c: All callers updated.
* process.c: Likewise.
* strace.c: Likewise.
* syscall.c: Likewise.
