`----
This happens when I'm mounting an ext4 fs with the option auto_da_alloc,
but not when I mount without it.
My current mount options are the following:
rw,relatime,nobarrier,delalloc,max_batch_time=50000,errors=remount-ro
and the filesystem has journal=writeback (I suspect that this may be the
bit that doesn't play nice with auto_da_alloc).
I don't really need auto_da_alloc (or, at least, think that I don't
), but I just wanted to report this.
If any further information is needed, just let me know.
Regards,
