When locking a file to access ACLs and xattrs etc, use explicit locking with inode_lock() instead of fh_lock(). This means that the calls to fh_fill_pre/post_attr() are also explicit which improves readability and allows us to place them only where they are needed. Only the xattr calls need pre/post information. When locking a file we don't need I_MUTEX_PARENT as the file is not a parent of anything, so we can use inode_lock() directly rather than the inode_lock_nested() call that fh_lock() uses.

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.
