Since v1:
- Removed unnecessary parentheses
---8<---
Failed GFP_ATOMIC allocations by the network stack result in dropped
packets, which will be received on a subsequent retransmit, and an
unnecessary, noisy warning with a kernel backtrace.
These warnings are harmless, but they still cause users to panic and
file bug reports over dropped packets. It would be better to hide the
failed allocation warnings and backtraces, and let retransmits handle
dropped packets quietly.
