This patch introduces a new "rescue=" mount option group for all mount options for data recovery. Different rescue sub options are seperated by ':'. E.g "ro,rescue=nologreplay:usebackuproot". The original plan was to use ';', but ';' needs to be escaped/quoted, or it will be interpreted by bash, similar to '|'. And obviously, user can specify rescue options one by one like: "ro,rescue=nologreplay,rescue=usebackuproot". The following mount options are converted to "rescue=", old mount options are deprecated but still available for compatibility purpose: - usebackuproot Now it's "rescue=usebackuproot" - nologreplay Now it's "rescue=nologreplay" Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
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.
