That way tools like "b4 am" automatically know where to trim things. So add a line like the following: -- >8 -- ...see "git mailinfo --help" for details. Also note that if you reply with an updated patch in a series include the "vX NN/MM" suffix, like "Subject: [PATCH v3 2/3] ..." so that b4 am knows to perform a "partial reroll". > From: Robert Richter <rrichter@amd.com> > Date: Tue, 19 Mar 2024 09:28:33 +0100 > Subject: [PATCH] cxl: Fix use of phys_to_target_node() outside of init section > > The CXL driver uses both functions phys_to_target_node() and > memory_add_physaddr_to_nid().

This patch is in addition to the other SRAT patches and can be applied directly to the cxl tree. That is why there is no version update here. But I replied to this series for reference. I saw the b4 shazam --no-parent option, would that help here?
