For zero-range that also extend the file we were sending this as a compound of two different operations; a fsctl to set-zero-data for the range and then an additional set-info to extend the file size. This does not work for Azure since it does not support this fsctl which leads to fallocate(FALLOC_FL_ZERO_RANGE) failing but still changing the file size. To fix this we un-compound this and send these two operations as separate commands, firsat one command to set-zero-data for the range and it this was successful we proceed to send a set-info to update the file size. This fixes xfstest generic/469 for Azure servers. Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.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.
