mainlining shenanigans
1bd85aa65d
Currently, we check the wb_err too early for directories, before all of the unsafe child requests have been waited on. In order to fix that we need to check the mapping->wb_err later nearer to the end of ceph_fsync. We also have an overly-complex method for tracking errors after blocklisting. The errors recorded in cleanup_session_requests go to a completely separate field in the inode, but we end up reporting them the same way we would for any other error (in fsync). There's no real benefit to tracking these errors in two different places, since the only reporting mechanism for them is in fsync, and we'd need to advance them both every time. Given that, we can just remove i_meta_err, and convert the places that used it to instead just use mapping->wb_err instead. That also fixes the original problem by ensuring that we do a check_and_advance of the wb_err at the end of the fsync op.

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.
