Locks have two sets of op arrays, fl_lmops for the lock manager (lockd or nfsd), fl_ops for the filesystem. The server-side lockd code has been setting its own fl_ops, which leads to confusion (and crashes) in the reexport case, where the filesystem expects to be the only one setting fl_ops. And there's no reason for it that I can see-the lm_get/put_owner ops do the same job. Reported-by: Daire Byrne <daire@dneg.com> Tested-by: Daire Byrne <daire@dneg.com> Signed-off-by: J.

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.
