I switched back to ext4 yesterday, because my btrfs fs got corrupted.
However mounting with lazytime doesn't work, neither specifying it in
/etc/fstab nor a manual remount. It looks like the option is simply
ignored.
Strace shows, e.g.:
# mount -o lazytime /boot
mount("/dev/sdc2", "/boot", "ext4", MS_LAZYTIME, NULL) = 0
EXT4-fs (sdc2): mounted filesystem with ordered data mode. Opts: (null)
/dev/sdc2 on /boot type ext4 (rw,relatime,data=ordered)
# mount -o remount,lazytime /var
mount("/dev/sdb2", "/var", 0x12c4460, MS_REMOUNT|MS_NOATIME|MS_LAZYTIME, NULL) = 0
EXT4-fs (sdb2): re-mounted. Opts: (null)
/dev/sdb2 on /var type ext4 (rw,noatime,data=ordered)
When I set "sb->s_flags |= MS_LAZYTIME;" unconditionally in
fs/ext4/super.c:5057 (just deleting the if statement), then lazytime
gets used when I remount.
I'm running the latest git tree (4.14.0-rc1).

Currently it seems that MS_LAZYTIME is supposed to be per sb option, even though I do not see a reason why it should not be per mnt options, in fact I'd prefer that. However the problem happened when e462ec50cb5fad19f6003a3d8087f4a0945dd2b1 switched from masking out per mnt flags to masking in per sb flags. However David missed SB_LAZYFLAG. The fix should be easy like this: diff --git a/fs/namespace.c b/fs/namespace.c index 54059b1..3b48ef1 100644 --- a/fs/namespace.c +++ b/fs/namespace.c @@ -2823,7 +2823,8 @@ long do_mount(const char *dev_name, const char __user *dir_name, SB_MANDLOCK | SB_DIRSYNC | SB_SILENT | - SB_POSIXACL); + SB_POSIXACL | + SB_LAZYTIME); if (flags & MS_REMOUNT) retval = do_remount(&path, flags, sb_flags, mnt_flags, I can send a proper patch, however maybe it would be better to convert it to per-mountpoint flags instead ?

Hi, I can't really see the problem on my system (4.14.0-rc1) # mount -o lazytime /dev/vdb /mnt/test # mount | grep vdb /dev/vdb on /mnt/test type ext4 (rw,relatime,lazytime,seclabel,data=ordered) Log says: EXT4-fs (vdb): mounted filesystem with ordered data mode. Opts: lazytime or even via remount # mount /dev/vdb /mnt/test # mount | grep vdb /dev/vdb on /mnt/test type ext4 (rw,relatime,seclabel,data=ordered) # mount -o remount,lazytime /mnt/test # mount | grep vdb /dev/vdb on /mnt/test type ext4 (rw,relatime,lazytime,seclabel,data=ordered) Log says: EXT4-fs (vdb): re-mounted. Opts: data=ordered,lazytime This is probably because I have older version of util-linux that did now knew about MS_LAZYTIME so it passed "lazytime" option down to the filesystem. So we're definitelly missing something in kernel for this to work properly. Indeed with newer version of util-linux, specifically the one containing commit v2.26-169-g8c7f073 I can reproduce.

Yes. It took me some time to figure out that this is a very recent Linux regression (since commit e462ec50cb5).
