From 399d7921299fc4f146bd62bfa6312382a5429bcc Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Tue, 31 Jan 2006 21:14:18 -0800 Subject: IB/mthca: Get rid of might_sleep() annotations 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 --- drivers/infiniband/hw/mthca/mthca_cq.c | 4 ---- 1 file changed, 4 deletions(-) (limited to 'drivers/infiniband/hw/mthca/mthca_cq.c') diff --git a/drivers/infiniband/hw/mthca/mthca_cq.c b/drivers/infiniband/hw/mthca/mthca_cq.c index 16a851b341f8..78d9cc119f33 100644 --- a/drivers/infiniband/hw/mthca/mthca_cq.c +++ b/drivers/infiniband/hw/mthca/mthca_cq.c @@ -696,8 +696,6 @@ int mthca_init_cq(struct mthca_dev *dev, int nent, u8 status; int i; - might_sleep(); - cq->ibcq.cqe = nent - 1; cq->is_kernel = !ctx; @@ -827,8 +825,6 @@ void mthca_free_cq(struct mthca_dev *dev, int err; u8 status; - might_sleep(); - mailbox = mthca_alloc_mailbox(dev, GFP_KERNEL); if (IS_ERR(mailbox)) { mthca_warn(dev, "No memory for mailbox to free CQ.\n"); -- cgit v1.2.2
