doc: Add rcutorture scripting to torture.txt

2020-02-27T15:03:14+00:00

For testing mainline, the kvm.sh rcutorture script is the preferred
approach to testing.  This commit therefore adds it to the torture.txt
documentation.

doc/RCU/listRCU: Update example function name

2020-02-27T15:03:13+00:00

listRCU.rst document gives an example with 'ipc_lock()', but the
function has dropped off by commit 82061c57ce93 ("ipc: drop
ipc_lock()").  Because the main logic of 'ipc_lock()' has melded in
'shm_lock()' by the commit, this commit updates the document to use
'shm_lock()' instead.

rcu: Remove kfree_rcu() special casing and lazy-callback handling

2020-01-24T18:24:31+00:00

This commit removes kfree_rcu() special-casing and the lazy-callback
handling from Tree RCU.  It moves some of this special casing to Tiny RCU,
the removal of which will be the subject of later commits.

This results in a nice negative delta.
