[PATCH 4.19 11/50] CIFS: Do not hide EINTR after sending network packets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Pavel Shilovsky <pshilov@xxxxxxxxxxxxx>

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.
