Subject: get_user_pages pinning: 2^22 page refs max?
Date: Wed, 1 May 2019 18:19:00 -0400 [thread overview]
Message-ID: <CAG48ez3C11j5On4kqwSBCZGtpS5XMohwEyT_2ei=aoaTex7D9Q@mail.gmail.com> (raw)
Regarding the LSFMM talk today:
So with the page ref bias, the maximum number of page references will
be something like 2^22, right? Is the bias only applied to writable
references or also readonly ones?
