peek_upto() checks against the end position and bails out before FILTER_SNAPSHOTS checks; this is because if we end up at a different inode number than the original search key none of the keys we see might be visibile in the current snapshot - we might be looking at inode in a completely different subvolume. But this is broken, because when we're iterating over extents we're checking against the extent start position to decide when to bail out, and the extent start position isn't monotonically increasing until after we've run FILTER_SNAPSHOTS. Fix this by adding a simple inode number check where the old bailout check was, and moving the main check to the correct position.

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.
