  "message": "Blackfin: optimize strncpy a bit\n\nAdd a little strncpy optimization which can easily cut boot time by 20%.\n\nWhen the kernel is booting with initramfs, it builds up the filesystem\nfrom a cpio archive by calling strncpy_from_user() via fs/namei.c\u0027s\ndo_getname() on every file in the archive (which can be lots) with a\nlength of PATH_MAX (1024).  This causes the dest of the strncpy to be\npadded with many NUL bytes.\n\nThis optimization mostly causes these NUL bytes to be padded with a call\nto memset() which is already optimized for filling memory quickly, but\nthe hardware loop helps a little bit as well.\n\nBoot time measured with \u0027loglevel\u003d0\u0027 so UART speed doesn\u0027t get in the way.\n\nSigned-off-by: Robin Getz \u003crobin.getz@analog.com\u003e\nSigned-off-by: Mike Frysinger \u003cvapier@gentoo.org\u003e\n",
