rmacklem 2011-04-27 18:19:26 UTC FreeBSD src repository Modified files: sys/rpc clnt.h clnt_rc.c clnt_vc.c rpcb_clnt.c Log: SVN rev 221127 on 2011-04-27 18:19:26Z by rmacklem This patch is believed to fix a problem in the kernel rpc for non-interruptible NFS mounts, where a kernel thread will seem to be stuck sleeping on "rpccon". The msleep() in clnt_vc_create() that was waiting to a TCP connect to complete would return ERESTART, since PCATCH was specified. Then the tsleep() in clnt_reconnect_call() would sleep for 1 second and then try again and again and... The patch changes the msleep() in clnt_vc_create() so it only sets the PCATCH flag for interruptible cases.
