Subject: [PATCH 0/6] Simplify hash_resize.c
Hi Paul,
This patch set updates hash_resize.c, which you suggested for me to
take over, and the related text.
I added a couple of Quick Quizzes as well, and in one of them,
I included your version of hash_resize.c.
Patch #1 updates hash_resize.c in the way I suggested. Note that
in this update, "#ifndef FCV_SNIPPET" blocks are used to hide
code for debugging (hash value checks) in code snippets.
This code can actually be compiled with "-DFCV_SNIPPET" to see
the performance without hash value checks.
Patch #2 adds a couple of Quick Quizzes. Your version of hash_resize.c
is added as hash_resize_s.c.
Patch #3 removes unnecessary folding in a code snippet.
Patch #4 adjusts a few sentence to the simpler approach.
Patch #5 adds another Quick Quiz.
Patch #6 adds an "#error" directive for the lack of rcu_barrier().
All of the updates in text would need your native eyes to be polished.
Thanks, Akira
PS:
I couldn't make out your concern of "if we ever want to iterate over
the hash table". Can you elaborate it?
