[patch 091/123] proc: make struct pid_entry::len unsigned

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Alexey Dobriyan <adobriyan@xxxxxxxxx>
Subject: 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.
