Linux kernel source tree for SHARP Brain series (PW-SH1 or later)
aee38af574
A bug existed in the XFS reflink code between v5.1 and v5.5 in which
the mapping for a COW IO was not trimmed to the mapping of the COW
extent that was found. This resulted in a too-short copy, and
corruption of other files which shared the original extent.
(This happened only when extent size hints were set, which bypasses
delalloc and led to this code path.)
This was (inadvertently) fixed upstream with
36adcbace24e "xfs: fill out the srcmap in iomap_begin"
and related patches which moved lots of this functionality to
the iomap subsystem.
Hence, this is a -stable only patch, targeted to fix this
corruption vector without other major code changes.

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.
