Resending patch to a slightly broader list for last minute check if
anyone objects. Although setting this particular socket option
(TCP_NODELAY) may not be as useful when corking/uncorking explicitly,
I want to doublecheck before removing them because there has been some
utility to the server allowing override of various sockopt options.
Samba server has long supported at least the following set of settable
socket options (although I don't know if the defaults are frequently
overridden now, by setting sockopts in smb.conf as used to be common
for the server).
SO_KEEPALIVE
SO_REUSEADDR
SO_BROADCAST
TCP_NODELAY
IPTOS_LOWDELAY
IPTOS_THROUGHPUT
SO_SNDBUF *
SO_RCVBUF *
SO_SNDLOWAT *
SO_RCVLOWAT *
* takes an integer argument rather than a boolean on/off
Any objections to removing the ability to set socket options
explicitly for the cifs network file system client?
