From: Tobias Klauser Date: Fri, 24 Mar 2006 11:15:34 +0000 (-0800) Subject: [PATCH] fs: Use ARRAY_SIZE macro X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e8c96f8c29d89af0c13dc2819a9a00575846ca18;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [PATCH] fs: Use ARRAY_SIZE macro Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove a duplicate of ARRAY_SIZE. Some trailing whitespaces are also deleted.
