X-Git-Tag: v2.6.13-rc4~130^2~157^2~19
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=0f9dc2b16884bb5957d010ed8e9114e771a05916;p=linux.git

[PATCH] RPC: Clean up socket autodisconnect

 Cancel autodisconnect requests inside xprt_transmit() in order to avoid
 races.
 Use more efficient del_singleshot_timer_sync()
