Subject: [PATCH 00/11] hashmap: bugfixes, safety fixes, and WIP improvements
Date: Mon, 26 Aug 2019 02:43:21 +0000 [thread overview]
Message-ID: <20190826024332.3403-1-e@80x24.org> (raw)
This started out as yak-shaving exercise to introduce the
"container_of" macro to make hashmap more flexible and
less error-prone.
So far I've ended up finding and fixing two real bugs in
patches 1/11 and 2/11 which should be fast-tracked.
Patches 3-9 are straightforward safety fixes to prevent future
bugs of the same type.
10-11 are work-in-progress changes to remove the limitation
of hashmap_entry being the first member of a struct. It's
also part of my ongoing agenda to spread Linux kernel idioms
into userspace and maybe get git.git hackers more comfortable
with kernel hacking (and vice-versa :>)
I'll try to continue the rest within the next few days.
The following changes since commit 745f6812895b31c02b29bdfe4ae8e5498f776c26:
First batch after Git 2.23 (2019-08-22 12:41:04 -0700)
