Since the SNAPSHOT_GET_IMAGE_SIZE, SNAPSHOT_AVAIL_SWAP_SIZE, and SNAPSHOT_ALLOC_SWAP_PAGE ioctls produce an loff_t result, and loff_t is always 64-bit even in the compat case, there's no reason to have the special compat handling for these ioctls. Just remove this unneeded code so that these ioctls call into snapshot_ioctl() directly, doing just the compat_ptr() conversion on the argument. (This unnecessary code was also causing a KMSAN false positive.) Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.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.
