| Subject: CIFS: Do not hide EINTR after sending network packets |
| |
| From: Pavel Shilovsky <pshilov@microsoft.com> |
| |
| commit ee13919c2e8d1f904e035ad4b4239029a8994131 upstream. |
| |
| Currently we hide EINTR code returned from sock_sendmsg() |
| and return 0 instead. This makes a caller think that we |
| successfully completed the network operation which is not |
| true. Fix this by properly returning EINTR to callers. |
