Bug description:
== SRU Request [Xenial][Artful] ==
== Justification ==
It is possible to hang zfs asynchronous reads if a read to a page that
is mmap'd onto the the file being read is the same offset in the
mapping as in the file. This is caused by two lock operations on the
page.
== Fix ==
Upstream ZFS fix to ensure the page is not double-locked during async
I/O of one or more pages.
== Testing ==
Create a zfs pool + zfs file system, run the reproducer program in
comment #28 on the zfs filesystem. Without the fix this can lock up,
with the fix this runs to completion.
== Regression Potential ==
Minimal, the locking fix addresses a fundamental bug in the locking
and this should not affect ZFS read/write I/O with this fix.
