The debug code relies on btree_trans_list being ordered so that it can resume on subsequent calls or lock restarts. However, it was using trans->locknig_wait.task.pid, which is incorrect since btree_trans objects are cached and reused - typically by different tasks. Fix this by switching to pointer order, and also sort them lazily when required - speeding up the btree_trans_get() fastpath. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> |

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 reStructuredText 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.
