From: OGAWA Hirofumi Date: Sun, 30 Oct 2005 01:15:50 +0000 (-0700) Subject: [PATCH] mm/msync.c cleanup X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b57b98d147ef98758886a39efb94f3254542c39b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [PATCH] mm/msync.c cleanup This is not problem actually, but sync_page_range() is using for exported function to filesystems. The msync_xxx is more readable at least to me.
