From 84f7a542f9e0191b6f7ab87881a050889576a5c4 Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Thu, 13 Feb 2014 14:48:14 -0500 Subject: [PATCH] staging/bcm: move IOCTL_BCM_TIME_SINCE_NET_ENTRY case out to its own function. bcm_char_ioctl is one of the longest non-generated functions in the kernel, at 1906 lines. Splitting it up into multiple functions should simplify this a lot.
