The patch titled
Subject: MMU notifier: use the new mmap locking API
has been removed from the -mm tree. Its filename was
mmu-notifier-use-the-new-mmap-locking-api.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Michel Lespinasse <walken@google.com>
Subject: MMU notifier: use the new mmap locking API
This use is converted manually ahead of the next patch in the series, as
it requires including a new header which the automated conversion would
miss.
