Add the following kfuncs to set and remove xattrs from BPF programs: bpf_set_dentry_xattr bpf_remove_dentry_xattr bpf_set_dentry_xattr_locked bpf_remove_dentry_xattr_locked The _locked version of these kfuncs are called from hooks where dentry->d_inode is already locked. Instead of requiring the user to know which version of the kfuncs to use, the verifier will pick the proper kfunc based on the calling hook.

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.
