kernel/linux.git/include/net/dropreason-core.h, branch v6.5.13Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.5.132023-04-21T03:20:49+00:00net: extend drop reasons for multiple subsystems2023-04-21T03:20:49+00:00Johannes Bergjohannes.berg@intel.com2023-04-19T12:52:53+00:00urn:sha1:071c0fc6fb919dcf29c676a842dda08a674877d7
Extend drop reasons to make them usable by subsystems
other than core by reserving the high 16 bits for a
new subsystem ID, of which 0 of course is used for the
existing reasons immediately.
To still be able to have string reasons, restructure
that code a bit to make the loopup under RCU, the only
user of this (right now) is drop_monitor.

net: move dropreason.h to dropreason-core.h2023-04-21T03:20:49+00:00Johannes Bergjohannes.berg@intel.com2023-04-19T12:52:52+00:00urn:sha1:5b8285cca6fed9bc5baabe2e5699a5a5c0d96371
This will, after the next patch, hold only the core
drop reasons and minimal infrastructure. Fix a small
kernel-doc issue while at it, to avoid the move
triggering a checker.
