Subject: proc: make struct pid_entry::len unsigned
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=623f594e7d20e4b5dac50aba5bd23822f2a95d6f;p=linux-beck.git

proc: make struct pid_entry::len unsigned

"unsigned int" is better on x86_64 because it most of the time it
autoexpands to 64-bit value while "int" requires MOVSX instruction.
