During review of subsequent patches, Dave and I noticed that this function doesn't work quite right -- accessing cur->bc_ino depends on the ROOT_IN_INODE flag, not LONG_PTRS. Fix that and the parentheses isssue. While we're at it, remove the piece that accesses cur->bc_ag, because block 0 of an AG is never part of a btree. Note: This changes the btree scrubber tracepoints behavior -- if the cursor has no buffer for a certain level, it will always report NULLFSBLOCK. It is assumed that anyone tracing the online fsck code will also be tracing xchk_start/xchk_done or otherwise be aware of what exactly is being scrubbed. Signed-off-by: Darrick J.

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.
