We found some bugs in the DAX conversion to XArray (and one bug which predated the XArray conversion). There were a couple of bugs in some of the higher-level functions, which aren't actually being called in today's kernel, but surfaced as a result of converting existing radix tree & IDR users over to the XArray. Some of the other changes to how the higher-level APIs work were also motivated by converting various users; again, they're not in use in today's kernel, so changing them has a low probability of introducing a bug. Dan can still trigger a bug in the DAX code with hot-offline/online, and we're working on tracking that down. -----BEGIN PGP SIGNATURE----- iQFIBAABCgAyFiEEejHryeLBw/spnjHrDpNsjXcpgj4FAlv542AUHHdpbGx5QGlu ZnJhZGVhZC5vcmcACgkQDpNsjXcpgj5BoAf/QZzbBcYuYMLMDYofvHKGlmk2yx/a ObUlxlQtXGHvPp3oC3rdwAvcN/KAMDpU0u+PXab2MnrNw5okhpS6ZwGODlkarNA4 XbVQNGbtEbACr1V3CWc0NzLbYm6JtGpMum0Wx9MVR/VdTnGArBLBYQMYa/c1YhKA vEBPf+w0j0QoCTAgPiIvq0aksuBQERUvjhlUvoaMY7F4sAhnaW558lvaEcc1xGxq 70+3cRPT6Uh12tEvi0LKP1NNEXebvQSftMvFEUPF2xo5z2v//KEobzv/anbojxQ8 BtxouIGSr4tME9g3xSpd9rTbUcW3bwDAhuWZvpP/ViRwW2UkEQonpApdaw== =0Ert -----END PGP SIGNATURE----- Merge tag 'xarray-4.20-rc4' of git://git.infradead.org/users/willy/linux-dax Pull XArray updates from Matthew Wilcox: "We found some bugs in the DAX conversion to XArray (and one bug which predated the XArray conversion).

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.
