dioread_nolock was originally disabled as a default option for bs < ps scenarios due to a data corruption issue. Since then, we've had some fixes in this area which address such issues. Enable dioread_nolock by default and remove the experimental warning message for bs < ps path. dioread for bs < ps has been tested on a 64k pagesize machine using: kvm-xfstest -C 3 -g auto with the following configs: 64k adv bigalloc_4k bigalloc_64k data_journal encrypt dioread_nolock dioread_nolock_4k ext3 ext3conv nojournal And no new regressions were seen compared to baseline kernel.

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.
