From: Andi Kleen Date: Sun, 19 Apr 2009 16:40:43 +0000 (+0200) Subject: Don't set relatime when noatime is specified X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=613cbe3d4870429bf2e816d4bbe3146d157ee5c1;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git Don't set relatime when noatime is specified Since commit 0a1c01c9477602ee8b44548a9405b2c1d587b5a2 ("Make relatime default") when a file system is mounted explicitely with noatime it gets both the MNT_RELATIME and MNT_NOATIME bits set. This shows up like this in /proc/mounts: /dev/xxx /yyy ext3 rw,noatime,relatime,errors=continue,data=writeback 0 0 That looks strange. The VFS uses noatime in this case, but both flags are set. So it's more a cosmetic issue, but still better to fix.
