From: Simon Wunderlich Date: Sat, 4 Sep 2010 23:58:23 +0000 (+0200) Subject: Staging: batman-adv: move queue counters into bat_priv X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7d02674f71e6369bb125354b23fd0abaa2edfcab;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git Staging: batman-adv: move queue counters into bat_priv to support multiple mesh devices later, we need to move global variables like the queues into corresponding private structs bat_priv of the soft devices. Note that this patch still has a lot of FIXMEs and depends on the global soft_device variable. This should be resolved later, e.g. by referencing the parent soft device in batman_if.
