Namjae Jeon 83dcedd554 ksmbd: fix infinite loop in ksmbd_conn_handler_loop() ... If kernel_recvmsg() return -EAGAIN in ksmbd_tcp_readv() and go round again, It will cause infinite loop issue. And all threads from next connections would be doing that. This patch add max retry count(2) to avoid it. kernel_recvmsg() will wait during 7sec timeout and try to retry two time if -EAGAIN is returned. And add flags of kvmalloc to __GFP_NOWARN and __GFP_NORETRY to disconnect immediately without retrying on memory alloation failure.
