From: Souptick Joarder
Date: Wed Jul 01 2020 - 02:09:38 EST


This series contains few clean up, minor bug fixes and
Convert get_user_pages() to pin_user_pages().

I'm compile tested this, but unable to run-time test,
so any testing help is much appriciated.

v2:
Address Dan's review comments to return -ERRNO for partially
mapped pages and changed the other patches in series accordingly.
Minor update in change logs.

v3:
Address review comment to invoke the right goto level when allocation
failed in patch[4/4].
