Hi Greg and Ted,
I've been looking at ext4 history the past couple of days seeing if the
patches that you attempted to apply from 4.17-rc1 were relevant and I
noticed a couple from previous 4.x versions that seem like they should
be applied here, as they are clean picks and tagged for stable:
74dae4278546 ("ext4: fix crashes in dioread_nolock mode")
c755e251357a ("ext4: fix deadlock between inline_data and ext4_expand_extra_isize_ea()")
I've been running them for the day and not had any issues (though I
didn't have any before). If there are any objections, let me know!
Thanks!
Nathan
