hexdump: do a few calculations ahead

2017-12-22T15:24:45+00:00

Instead of doing calculations in each case of different groupsize let's do them beforehand. While there, change the switch to an if-else-if construction. Signed-off-by: Andy Shevchenko Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

hexdump: fix ascii column for the tail of a dump

2017-12-22T15:24:44+00:00

In the current implementation we have a floating ascii column in the tail of the dump. For example, for row size equal to 16 the ascii column as in following table group size \ length 8 12 16 1 50 50 50 2 22 32 42 4 20 29 38 8 19 - 36 This patch makes it the same independently of amount of bytes dumped. The change is safe since all current users, which use ASCII part of the dump, rely on the group size equal to 1. The patch doesn't change behaviour for such group size (see the table above).

lib: introduce upper case hex ascii helpers

2017-04-11T08:57:15+00:00

To be able to use the hex ascii functions in case sensitive environments the array hex_asc_upper[] and the needed functions for hex_byte_pack_upper() are introduced. Signed-off-by: Andre Naujoks Signed-off-by: David S. Miller
