Some fuse servers need to prune their caches, which can only be done if the
kernel's own dentry/inode caches are pruned first to avoid dangling
references.
Add FUSE_NOTIFY_PRUNE, which takes an array of node ID's to try and get rid
of. Inodes with active references are skipped.
A similar functionality is already provided by FUSE_NOTIFY_INVAL_ENTRY with
the FUSE_EXPIRE_ONLY flag. Differences in the interface are
FUSE_NOTIFY_INVAL_ENTRY:
- can only prune one dentry
- dentry is determined by parent ID and name
- if inode has multiple aliases (cached hard links), then they would have
to be invalidated individually to be able to get rid of the inode
FUSE_NOTIFY_PRUNE:
- can prune multiple inodes
- inodes determined by their node ID
- aliases are taken care of automatically

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.
