Hi,
I've been triggering ext4 troubles out of some experimental autonuma
code if I set knumad frequency rates very high.
The first patch looks fairly safe, but the second patch I've no idea
if it's correct and if damages stuff instead of fixing it, but clearly
it fixes the -EINVAL problem for me and it looks like to work fine now.
[PATCH 1/2] ext4: avoid hangs in ext4_da_should_update_i_disksize()
[PATCH 2/2] ext4: ext4_discard_partial_page_buffers_no_lock() wrong parameters
If you make alternate fixes for this let me know and I can test
them. I can reproduce both issues instantly.
Thanks,
Andrea
