If a client doesn't have Fx caps on a directory, it will get errors while
trying encrypt it:
ceph: handle_cap_grant: cap grant attempt to change fscrypt_auth on non-I_NEW inode (old len 0 new len 48)
fscrypt (ceph, inode 1099511627812): Error -105 getting encryption context
A simple way to reproduce this is to use two clients:
client1 # mkdir /mnt/mydir
client2 # ls /mnt/mydir
client1 # fscrypt encrypt /mnt/mydir
client1 # echo hello > /mnt/mydir/world
This happens because, in __ceph_setattr(), we only initialize
ci->fscrypt_auth if we have Ax and ceph_fill_inode() won't use the
fscrypt_auth received if the inode state isn't I_NEW. Fix it by allowing
ceph_fill_inode() to also set ci->fscrypt_auth if the inode doesn't have
it set already.

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.
