From: Deepa Dinamani Date: Sun, 7 Feb 2016 07:57:21 +0000 (-0800) Subject: btrfs: Replace CURRENT_TIME by current_fs_time() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=04b285f35e2086b69682c7ed054aa35eebea9f72;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git btrfs: Replace CURRENT_TIME by current_fs_time() CURRENT_TIME macro is not appropriate for filesystems as it doesn't use the right granularity for filesystem timestamps. Use current_fs_time() instead.
