X-Git-Tag: v3.6-rc1~29^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b042414feb240df5f5911b9bca39b61e6738e814;p=pandora-kernel.git nfs: increase number of permitted callback connections. By default a sunrpc service is limited to (N+3)*20 connections where N is the number of threads. This is 80 when N==1. If this number is exceeded a warning is printed suggesting that the number of threads be increased. However with services which run a single thread, this is impossible. For such services there is a ->sv_maxconn setting that can be used to forcibly increase the limit, and silence the message. This is used by lockd. The nfs client uses a sunrpc service to handle callbacks and it too is single-threaded, so to avoid the useless messages, and to allow a reasonable number of concurrent connections, we need to set ->sv_maxconn. 1024 seems like a good number.
