[ Upstream commit ff77042296d0a54535ddf74412c5ae92cb4ec76a ] Steps to reproduce: BLKRESETZONE zone 0 // force EIO pwrite(fd, buf, 4096, 4096); [issue more IO including zone ioctls] It will start failing randomly including IO to unrelated zones because of ->error "reuse". Trigger can be partition detection as well if test is not run immediately which is even more entertaining. The fix is of course to clear ->error where necessary.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
