[PATCH] libceph: print more info for short message header

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If an osd client response message arrives that has a front section
that's too big for the buffer set aside to receive it, a warning
gets reported and a new buffer is allocated.

The warning says nothing about which connection had the problem.
Add the peer type and number to what gets reported, to be a bit more
informative.
