The might_sleep() annotations in mthca are silly -- they all occur shortly before calls that will end up in core functions like kmalloc() that will print the same warning in an unsafe context anyway. In fact, beyond cluttering the source, we're actually bloating text with CONFIG_DEBUG_SPINLOCK_SLEEP and/or CONFIG_PREEMPT_VOLUNTARY set. With both options set, getting rid of the might_sleep()s saves a lot: add/remove: 0/0 grow/shrink: 0/7 up/down: 0/-171 (-171) function old new delta mthca_pd_alloc 132 109 -23 mthca_init_cq 969 946 -23 mthca_mr_alloc 592 568 -24 mthca_pd_free 67 42 -25 mthca_free_mr 219 194 -25 mthca_free_cq 570 545 -25 mthca_fmr_alloc 742 716 -26 Signed-off-by: Roland Dreier <rolandd@cisco.com> |
