Eric Sandeen <sandeen@redhat.com> says: pstore used mount_single, which used to transparently do a remount operation on a fresh mount of an existing superblock. The new get_tree_single does not do this, but prior discussion on fsdevel seems to indicate that this isn't expected to be a problem. We can watch for issues. devpts is just a forward port from work dhowells did already, and it seems straightforward. I left error messages as they are rather than converting to the mount API message channel for now. devtmpfs was already converted, but left a .mount in place, rather than using .get_tree. The solution to this is ... unique so some scrutiny is probably wise. The last patch removes reconfigure_single, mount_single, and compare_single because no users remain, but we could also wait until all conversions are done, and remove all infrastructure at that time instead, if desired. * patches from https://lore.kernel.org/r/20250205213931.74614-1-sandeen@redhat.com: vfs: remove some unused old mount api code devtmpfs: replace ->mount with ->get_tree in public instance vfs: Convert devpts to use the new mount API pstore: convert to the new mount API Link: https://lore.kernel.org/r/20250205213931.74614-1-sandeen@redhat.com Signed-off-by: Christian Brauner <brauner@kernel.org>
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 reStructuredText 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.
