Subject: [PATCH 5.10 23/29] tools/vm/page-types: remove dependency on opt_file for idle page tracking
Date: Fri, 8 Oct 2021 13:28:10 +0200 [thread overview]
Message-ID: <20211008112717.744370355@linuxfoundation.org> (raw)
In-Reply-To: <20211008112716.914501436@linuxfoundation.org>
From: Changbin Du <changbin.du@gmail.com>
[ Upstream commit ebaeab2fe87987cef28eb5ab174c42cd28594387 ]
Idle page tracking can also be used for process address space, not only
file mappings.
Without this change, using with '-i' option for process address space
encounters below errors reported.
$ sudo ./page-types -p $(pidof bash) -i
mark page idle: Bad file descriptor
mark page idle: Bad file descriptor
mark page idle: Bad file descriptor
