When we started stashing the key being overwritten in btree_insert_entry, this introduced a typical iterator invalidation problem, triggered by btree node splits or resorts. Previously, dealt with this by unconditionally re-validating those stashed pointers in the transaction commit path. This patch gets rid of that by doing it only when needed, in bch2_trans_node_add() or bch2_trans_node_reinit_iter(). 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 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.
