I'm announcing the release of the 6.1.93 kernel.
All users of the 6.1 kernel series must upgrade.
The updated 6.1.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.1.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

- The new SKB is updated with the necessary information (protocol,

+Dynamic RX Buffers (DRB)
+------------------------
+
+Each RX descriptor in the RX ring is a single memory page (which is either 4KB
+or 16KB long depending on system's configurations).
+To reduce the memory allocations required when dealing with a high rate of small
+packets, the driver tries to reuse the remaining RX descriptor's space if more
+than 2KB of this page remain unused.
+
+A simple example of this mechanism is the following sequence of events:
+
+::
+
+ 1. Driver allocates page-sized RX buffer and passes it to hardware
+ +----------------------+
+ |4KB RX Buffer |
+ +----------------------+
+
+ 2. A 300Bytes packet is received on this buffer
+
+ 3. The driver increases the ref count on this page and returns it back to
+ HW as an RX buffer of size 4KB - 300Bytes = 3796 Bytes
+ +----+--------------------+
+ |****|3796 Bytes RX Buffer|
+ +----+--------------------+
+
+This mechanism isn't used when an XDP program is loaded, or when the
+RX packet is less than rx_copybreak bytes (in which case the packet is
+copied out of the RX buffer into the linear part of a new skb allocated
+for it and the RX buffer remains the same size, see `RX copybreak`_).
