[ Upstream commit 38d222b3163f7b7d737e5d999ffc890a12870e36 ] It's possible for v9fs_fid_find "find by dentry" branch to not turn up anything despite having an entry set (because e.g. uid doesn't match), in which case the calling code will generally make an extra lookup to the server. In this case we might have had better luck looking by inode, so fall back to look up by inode if we have one and the lookup by dentry failed.

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.
