When a disk is removed with in-flight I/O, the application needs to wait for 30 seconds (depending on the timeout configuration) to hear back from the kernel. Xingui tried to fix this issue by aborting the ATA link for SATA devices[1], however this approach left the SAS devices unresolved. Try to fix this issue by aborting all in-flight requests when the device is gone. This is implemented by iterating over the tagset.

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.
