  "message": "string: memchr_inv() speed improvements\n\n- Generate a 64-bit pattern more efficiently\n\nmemchr_inv needs to generate a 64-bit pattern filled with a target\ncharacter.  The operation can be done by more efficient way.\n\n- Don\u0027t call the slow check_bytes() if the memory area is 64-bit aligned\n\nmemchr_inv compares contiguous 64-bit words with the 64-bit pattern as\nmuch as possible.  The outside of the region is checked by check_bytes()\nthat scans for each byte.  Unfortunately, the first 64-bit word is\nunexpectedly scanned by check_bytes() even if the memory area is aligned\nto a 64-bit boundary.\n\nBoth changes were originally suggested by Eric Dumazet.\n\nSigned-off-by: Akinobu Mita \u003cakinobu.mita@gmail.com\u003e\nSuggested-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Brian Norris \u003ccomputersforpeace@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
