Modified files:
lib/libc/gen scandir.c
Log:
scandir(3) previously used st_size to obtain an initial estimate
of the array length needed to store all the directory entries.
Although BSD has historically guaranteed that st_size is the size
of the directory file, POSIX does not, and more to the point, some
recent filesystems such as ZFS use st_size to mean something else.
The fix is to not stat the directory at all, set the initial
array size to 32 entries, and realloc it in powers of 2 if that
proves insufficient.
