-Subject: 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.
-
-Fixes: 0626e66 ("cifsd: add server handler for central processing and tranport layers")
