fs/proc/internal.h: shuffle "struct pde_opener"
List iteration takes more code than anything else which means embedded
list_head should be the first element of the structure.
Space savings:
add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-18 (-18)
Function old new delta
close_pdeo 228 227 -1
proc_reg_release 86 82 -4
proc_entry_rundown 143 139 -4
proc_reg_open 298 289 -9
