Commit abc02e5602f7 ("NFSD: Support write delegations in LAYOUTGET")
added NFSD_MAY_OWNER_OVERRIDE to the access flags passed from
nfsd4_layoutget() to fh_verify(). This causes LAYOUTGET to fail for
executable-only files, and causes xfstests generic/126 to fail on
pNFS SCSI.
To allow read access to executable-only files, what we really want is:
1. The "permissions" portion of the access flags (the lower 6 bits)
must be exactly NFSD_MAY_READ
2. The "hints" portion of the access flags (the upper 26 bits) can
contain any combination of NFSD_MAY_OWNER_OVERRIDE and
NFSD_MAY_READ_IF_EXEC

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 reStructuredText 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.
