From c846d8da5640a6c61d57e2c14a1a6d74b9c643b0 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Wed, 14 Mar 2018 19:57:24 -0700 Subject: [PATCH] mlx5: Remove call to ida_pre_get The mlx5 driver calls ida_pre_get() in a loop for no readily apparent reason. The driver uses ida_simple_get() which will call ida_pre_get() by itself and there's no need to use ida_pre_get() unless using ida_get_new(). Signed-off-by: Matthew Wilcox Signed-off-by: David S.
