This is a per-sb list now, but that makes it difficult to tell when the cap is the last dirty one associated with the session. Switch this to be a per-session list, but continue using the mdsc->cap_dirty_lock to protect the lists. This list is only ever walked in ceph_flush_dirty_caps, so change that to walk the sessions array and then flush the caps for inodes on each session's list. If the auth cap ever changes while the inode has dirty caps, then move the inode to the appropriate session for the new auth_cap. Also, ensure that we never remove an auth cap while the inode is still on the s_cap_dirty list.

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.
