Subject: [RFC PATCH 56/76] afs: Pass page into dirty region helpers to provide THP size
Date: Fri, 20 Nov 2020 15:14:31 +0000
Message-ID: <160588527183.3465195.16107942526481976308.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <160588455242.3465195.3214733858273019178.stgit@warthog.procyon.org.uk>

Pass a pointer to the page being accessed into the dirty region helpers so
that the size of the page can be determined in case it's a transparent huge
page.

This also required the page to be passed into the afs_page_dirty trace
point - so there's no need to specifically pass in the index or private
data as these can be retrieved directly from the page struct.
