*** empty log message ***
(vfprintf): Only call __libc_cleanup_region_end if USE_IN_LIBIO, thus matching the sense of the tests around __libc_cleanup_region_start at the front of the function. * stdio-common/vfscanf.c: Include <libc-lock.h>. (UNLOCK_STREAM) [! USE_IN_LIBIO]: Call __libc_cleanup_region_end, not __libc_cleanup_region_start.
