Ilya Dryomov b91a7bdca4 rbd: don't assert on writes to snapshots 
The check added in commit 721c7fc701 ("block: fail op_is_write()
requests to read-only partitions") was lifted in commit a32e236eb9
("Partially revert "block: fail op_is_write() requests to read-only
partitions"").  Basic things like user triggered writes and discards
are still caught, but internal kernel users can submit anything.  In
particular, ext4 will attempt to write to the superblock if it detects
errors in the filesystem, even if the filesystem is mounted read-only
on a read-only partition.

The assert is overkill regardless.

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.
