[ Upstream commit 5d2ae14276e698c76fa0c8ce870103f343b38263 ]
Commit ef295ecf090d modified the Linux kernel such that the bottom bits
of the bi_opf member contain the operation instead of the topmost bits.
That commit did not update the comment next to bi_opf. Hence this patch.
From commit ef295ecf090d:
-#define bio_op(bio) ((bio)->bi_opf >> BIO_OP_SHIFT)
+#define bio_op(bio) ((bio)->bi_opf & REQ_OP_MASK)

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.
