[Linux-kernel-mentees][PATCH v6 1/2] sgi-gru: Convert put_page() to put_user_page*()

From: Bharath Vedartham
Date: Sun Aug 18 2019 - 15:39:29 EST

For pages that were retained via get_user_pages*(), release those pages
via the new put_user_page*() routines, instead of via put_page() or

This is part a tree-wide conversion, as described in commit fc1d8e7cca2d
("mm: introduce put_user_page*(), placeholder versions").
