The cache is only used if it's completed, not while it's still being filled; this constraint could be lifted later, if it turns out to be useful. Introduce state in struct fuse_file that indicates the position within the cache. After a seek, reset the position to the beginning of the cache and search the cache for the current position. If the current position is not found in the cache, then fall back to uncached readdir. It can also happen that page(s) disappear from the cache, in which case we must also fall back to uncached readdir. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
