Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

With the Octopus release, the MDS will hand out directory create caps. If we have Fxc caps on the directory, and complete directory information or a known negative dentry, then we can return without waiting on the reply, allowing the open() call to return very quickly to userland. We use the normal ceph_fill_inode() routine to fill in the inode, so we have to gin up some reply inode information with what we'd expect the newly-created inode to have. The client assumes that it has a full set of caps on the new inode, and that the MDS will revoke them when there is conflicting access. This functionality is gated on the wsync/nowsync mount options.

README
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.
