When attempting an NFSv4 mount, a Solaris NFSv4 client builds a single large COMPOUND that chains a series of LOOKUPs to get to the pseudo filesystem root directory that is to be mounted. The Linux NFS server's current maximum of 16 operations per NFSv4 COMPOUND is not large enough to ensure that this works for paths that are more than a few components deep. Since NFSD_MAX_OPS_PER_COMPOUND is mostly a sanity check, and most NFSv4 COMPOUNDS are between 3 and 6 operations (thus they do not trigger any re-allocation of the operation array on the server), increasing this maximum should result in little to no impact. The ops array can get large now, so allocate it via vmalloc() to help ensure memory fragmentation won't cause an allocation failure.

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.
