proc: rearrange args Rearrange args for smaller code. lookup revolves around memcmp() which gets len 3rd arg, so propagate length as 3rd arg. readdir and lookup add additional arg to VFS ->readdir and ->lookup, so better add it to the end. Space savings on x86_64: add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-18 (-18) Function old new delta proc_readdir 22 13 -9 proc_lookup 18 9 -9 proc_match() is smaller if not inlined, I promise!
