nochanges means "we cannot issue writes at all"; it's possible to go into a pseudo read-write mode where we pin dirty metadata in memory, which is used for fsck in dry run mode and doing journal replay on a read only mount, but we do not want to allow an actual read-write mount in nochanges mode. But we do always want to allow early read-write, during recovery - this patch clarifies that. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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.
