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.

Pull misc vfs updates from Christian Brauner: "This contains a pile of various smaller fixes. Most of them aren't very interesting so this just highlights things worth mentioning: - Various filesystems contained the same little helper to convert from the mode of a dentry to the DT_* type of that dentry. They have now all been switched to rely on the generic fs_umode_to_dtype() helper. All custom helpers are removed (Jeff) - Fsnotify now reports ACCESS and MODIFY events for splice (Chung-Chiang Cheng) - After converting timerfd a long time ago to rely on wait_event_interruptible_*() apis, convert eventfd as well. This removes the complex open-coded wait code (Wen Yang) - Simplify sysctl registration for devpts, avoiding the declaration of two tables. Instead, just use a prefixed path with register_sysctl() (Luis) - The setattr_should_drop_sgid() helper is now exported so NFS can use it. By switching NFS to this helper an NFS setgid inheritance bug is fixed (me)" * tag 'v6.4/vfs.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fs: hfsplus: remove WARN_ON() from hfsplus_cat_{read,write}_inode() pnode: pass mountpoint directly eventfd: use wait_event_interruptible_locked_irq() helper splice: report related fsnotify events fs: consolidate duplicate dt_type helpers nfs: use vfs setgid helper Update relatime comments to include equality fs/buffer: Remove redundant assignment to err fs_context: drop the unused lsm_flags member fs/namespace: fnic: Switch to use %ptTd Documentation: update idmappings.rst devpts: simplify two-level sysctl registration for pty_kern_table eventpoll: align comment with nested epoll limitation
