commita75ca93031upstream. commite7bf90e5af("block/bio-integrity: fix a memory leak bug") added a kfree() for 'buf' if bio_integrity_add_page() returns '0'. However, the object will be freed in bio_integrity_free() since 'bio->bi_opf' and 'bio->bi_integrity' were set previousy in bio_integrity_alloc().

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.
