Subject: [PATCH] proc: make struct struct map_files_info::len unsigned int
Date: Sat, 29 Oct 2016 19:11:23 +0300 [thread overview]
Message-ID: <20161029161123.GG1246@avx2> (raw)
Linux doesn't support 4GB+ filenames in /proc, so unsigned long is too much.
MOV r64, r/m64 is smaller than MOV r32, r/m32.
