Subject: [GIT PULL rcu/next] RCU commits for 4.17
Date: Sat, 10 Mar 2018 07:57:17 -0800 [thread overview]
Message-ID: <20180310155717.GA10068@linux.vnet.ibm.com> (raw)
Hello, Ingo!
This pull request contains the following changes:
1. Miscellaneous fixes, perhaps most notably removing obsolete
code whose only purpose in life was to gather information for
the now-removed RCU debugfs facility. Other notable changes
include removing NO_HZ_FULL_ALL in favor of the nohz_full kernel
boot parameter, minor optimizations for expedited grace periods,
some added tracing, creating an RCU-specific workqueue using Tejun's
new WQ_MEM_RECLAIM flag, and several cleanups to code and comments.

2. SRCU cleanups and optimizations.
http://lkml.kernel.org/r/20180226215614.GA31616@linux.vnet.ibm.com
3. Torture-test updates, perhaps most notably the adding of ARMv8
support, but also including numerous cleanups and usability fixes.
http://lkml.kernel.org/r/20180307172627.GA15805@linux.vnet.ibm.com
All of these changes have been subjected to 0day Test Robot and -next
testing, and are available in the git repository at:
