hex_dump_to_buffer:
Removes casts to type for non-1 group sizes
Used by: fs/ext(3|4)super.c, fs/jfs
If someone really dislikes this change, please say so.
I think casting to type in a hex dump odd, especially
for mixed type structures.
If you want an array of type dumper, it probably
shouldn't be called hex_dump_to_buffer.
Groups by arbitrary size
print_hex_dump:
Removes rowsize argument
Reduces linebuf stack use to ~120 bytes
prefix:25 + address:20 + data:48 + ascii:20)
Aligns multiline ascii output
Changes return to size_t, number of bytes actually output
include/linux/kernel.h
Removes hex_asc define
Updates hex_dump prototypes
mm/slub.c
Use print_hex_dump
The rest are trivial conversions to new argument list.
size before:
text data bss dec hex filename
1142 0 0 1142 476 lib/hexdump.o
size after:
text data bss dec hex filename
823 0 0 823 337 lib/hexdump.o
