Hi!

Ubifs seems to have atime support these days:

          sb->s_flags |= SB_ACTIVE;
#ifndef CONFIG_UBIFS_ATIME_SUPPORT
          sb->s_flags |= SB_NOATIME;
#else
          ubifs_msg(c, "full atime support is enabled.");

#endif

Which can be configured at compile-time, but no option to disable it at runtime. What is going on there?

UBIFS: parse noatime
UBIFS error (ubi1:0 pid 94): ubifs_parse_options.constprop.5:
unrecognized mount option "noatime" e
mount: mounting ubi1:log_volume on /mnt/log failed: Invalid argument

Filesystems don't parse the "noatime" string, it is job of the mount tool to translate it to the MS_NOATIME mount flag.

Thanks,

Ahha. I was using busybox version of mount. I guess I should check its config. Thanks!
