The code EXT4_IOC_SWAP_BOOT ioctl hasn't been updated in a while, and it's a bit broken with respect to more modern ext4 kernels, especially metadata checksums. Other problems fixed with this commit: * Don't allow installing a DAX, swap file, or an encrypted file as a boot loader. * Respect the immutable and append-only flags. * Wait until any DIO operations are finished *before* calling truncate_inode_pages(). * Don't swap inode->i_flags, since these flags have nothing to do with the inode blocks --- and it will give the IMA/audit code heartburn when the inode is evicted.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
