Sebastian Andrzej Siewior says: ==================== net: dev: PREEMPT_RT fixups. this series removes or replaces preempt_disable() and local_irq_save() sections which are problematic on PREEMPT_RT. Patch 2 makes netif_rx() work from any context after I found suggestions for it in an old thread. Should that work, then the context-specific variants could be removed. v2…v3: - #2 - Export __netif_rx() so it can be used by everyone. - Add a lockdep assert to check for interrupt context. - Update the kernel doc and mention that the skb is posted to backlog NAPI. - Use __netif_rx() also in drivers/net/*.c. - Added Toke''s review tag and kept Eric's desptite the changes made. v1…v2: - #1 and #2 - merge patch 1 und 2 from the series (as per Toke). - updated patch description and corrected the first commit number (as per Eric). - #2 - Provide netif_rx() as in v1 and additionally __netif_rx() without local_bh disable()+enable() for the loopback driver. __netif_rx() is not exported (loopback is built-in only) so it won't be used drivers. If this doesn't work then we can still export/ define a wrapper as Eric suggested. - Added a comment that netif_rx() considered legacy. - #3 - Moved ____napi_schedule() into rps_ipi_queued() and renamed it napi_schedule_rps(). https://lore.kernel.org/all/20220204201259.1095226-1-bigeasy@linutronix.de/ v1: https://lore.kernel.org/all/20220202122848.647635-1-bigeasy@linutronix.de ==================== Signed-off-by: David S.

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.
