Subject: proc: make struct struct map_files_info::len unsigned int
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9a87fe0d7c2d4fb62255cb69088da5a812df3516;p=linux-beck.git

proc: make struct struct map_files_info::len unsigned int

Linux doesn't support 4GB+ filenames in /proc, so unsigned long is too
much.

MOV r64, r/m64 is larger than MOV r32, r/m32.
