Subject: [PATCH] SUNRPC: don't reencode when looping in call transmit.
X-Git-Tag: v2.6.15-rc1~54
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=940e3318c36394939d805e797d7be39ddaaa7911;p=pandora-kernel.git

[PATCH] SUNRPC: don't reencode when looping in call transmit.

If the call to xprt_transmit() fails due to socket buffer space
exhaustion, we do not need to re-encode the RPC message when we
loop back through call_transmit.

Re-encoding can actually end up triggering the WARN_ON() in
call_decode() if we re-encode something like a read() request and
auth->au_rslack has changed.
It can also cause us to increment the RPCSEC_GSS sequence number
beyond the limits of the allowed window.
