Pull file locking updates from Jeff Layton: "The main change here is to add the new locks_inode_context helper, and convert all of the places that dereference inode->i_flctx directly to use that instead. There is a new helper to indicate whether any locks are held on an inode. This is mostly for Ceph but may be usable elsewhere too. Andi Kleen requested that we print the PID when the LOCK_MAND warning fires, to help track down applications trying to use it. Finally, we added some new warnings to some of the file locking functions that fire when the ->fl_file and filp arguments differ. This helped us find some long-standing bugs in lockd. Patches for those are in Chuck Lever's tree and should be in his v6.2 PR. After that patch, people using NFSv2/v3 locking may see some warnings fire until those go in. Happy Holidays!" * tag 'locks-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux: Add process name and pid to locks warning nfsd: use locks_inode_context helper nfs: use locks_inode_context helper lockd: use locks_inode_context helper ksmbd: use locks_inode_context helper cifs: use locks_inode_context helper ceph: use locks_inode_context helper filelock: add a new locks_inode_context accessor function filelock: new helper: vfs_inode_has_locks filelock: WARN_ON_ONCE when ->fl_file and filp don't match
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.
