Regarding xfs_buf_alloc_pages(), it is not using __GFP_ACCOUNT

It probably should, actually. Sorry, somewhat off-topic, but we've
seen this consume quite large amounts of memory. __GFP_ACCOUNT and
vmstat tracking seems overdue for this one.

If this will be required, you can use
[PATCH mm v5] memcg: enable memory accounting in __alloc_pages_bulk
https://lkml.org/lkml/2021/10/14/197

As far as I understand it will not be used right now,
however I decided to submit it anyway, perhaps it may be needed later.

Thank you,
