[PATCH v3 7/7] pppoatm: do not inline pppoatm_may_send()

From: Krzysztof Mazur
Date: Tue Nov 06 2012 - 17:21:11 EST


The pppoatm_may_send() is quite heavy and it's called three times
in pppoatm_send() and inlining costs more than 200 bytes of code
(more than 10% of total pppoatm driver code size).

add/remove: 1/0 grow/shrink: 0/1 up/down: 132/-367 (-235)
function old new delta
pppoatm_may_send - 132 +132
pppoatm_send 900 533 -367
