This reverts commit 8a08c5fd89b447a7de7eb293a7a274c46b932ba2. It turns out while this is a perfectly valid and long overdue thing to do for user initiated discards / zeroing from the ioctl handler, it actually breaks file system use of the discard helper by interrupting in places the file system doesn't expect, and by leaving the bio chain in a state that the file system callers of (at least) __blkdev_issue_discard do not expect. Revert the change for now, we'll redo it for the next merge window after refactoring the code to better split the file system vs ioctl callers and cleaning up a few other loose ends.

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.
