Commit Message

Li Zhijian Jan. 9, 2024, 8:32 a.m. UTC
commit 9ac01f434a1e ("RDMA/rxe: Extend dbg log messages to err and info")
newly added this info. But it did only show null device when
the rdma_rxe is being loaded because dev_name(rxe->ib_dev->dev)
has not yet been assigned at the moment:

"(null): rxe_set_mtu: Set mtu to 1024"

Remove it to silent this message, check the mtu from it backend link
instead if needed.

I'd like to keep this statement so I can tell if the mtu setup was
successful or not.

Thanks. Maybe move this "commit 9ac01f434a1e ("RDMA/rxe: Extend dbg log 
messages to err and info")" to Fixes tag, is it better?

During the module loading, once it's loaded successfully, the mtu is set as well.

The another caller rxe_notify()->rxe_set_mtu() already had its own dbg message for this,
people can enable the dbg if needed.

Anyway, I'm open to your point.


Thanks

IMHO, this print can be safely removed.
