hva_to_pfn_remapped() calls fixup_user_fault(), which has already handled the retry gracefully. Even if "unlocked" is set to true, it means that we've got a VM_FAULT_RETRY inside fixup_user_fault(), however the page fault has already retried and we should have the pfn set correctly. No need to do that again. Signed-off-by: Peter Xu <peterx@redhat.com> Message-Id: <20200416155906.267462-1-peterx@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
