Since libcfs no longer builds for user land we can
move the TCPIP abstraction that exist to the LNET
layer which is the only place that uses it. Also
the migrated code will use native linux kernel
APIs directly instead of with wrappers.

yes. path changed for libcfs.h. so that was updated.
but there was also a new line
#include "../../include/linux/lnet/lib-lnet.h"
should that be part of moving the file also?

That is handle the move of some of the LNet function declarations in libcfs.h
to lib-lnet.h. That happens in patch number 4 of this series. I was trying to
minimize the diff between the tip of the Lustre development branch and
the upstream client.

Please generate patches in -M format, so I can see the rename properly,
as it is, this is too messy for me to review.
Please fix up and resend.

Adding this to the .gitconfig works too

There is no reason to have a one line exported function
libcfs_sock_release. Instead we can call sock_release directly.

Another one of those silly one line wrappers which is not
needed. Replace libcfs_sock_abort_accept wrapper with a
direct call to wake_up_all on the lnet_acceptor_state sock.

* [lustre-devel] [PATCH v4 4/7] staging:lustre: rename tcpip handling functions to lnet_* prefix

To: lustre-devel
With all the TCPIP handling done in the lnet layer we should
rename all the functions with the prefix lnet_*. One other
change done was changing the remove argument of lnet_sock_getaddr
from a int to a bool.

^ permalink raw reply related [flat|nested] 36+ messages in thread* [PATCH v4 4/7] staging:lustre: rename tcpip handling functions to lnet_* prefix
@ 2015-06-03 19:57 ` James Simmons
0 siblings, 0 replies; 36+ messages in thread
From: James Simmons @ 2015-06-03 19:57 UTC (permalink / raw)
To: Greg Kroah-Hartman, devel, Oleg Drokin, Andreas Dilger
Cc: Linux Kernel Mailing List, lustre-devel, James Simmons
With all the TCPIP handling done in the lnet layer we should
rename all the functions with the prefix lnet_*. One other
change done was changing the remove argument of lnet_sock_getaddr
from a int to a bool.

thats two different change.
and apart from this:
1) the function declarations were renamed and moved from
lustre/include/linux/libcfs/libcfs.h to drivers/staging/lustre/include/linux/lnet/lib-lnet.h
2) some functions you have changed the coding style. like:
- rc = libcfs_sock_getaddr(conn->ksnc_sock, 0,
- &conn->ksnc_myipaddr, NULL);
+ rc = lnet_sock_getaddr(conn->ksnc_sock, 0, &conn->ksnc_myipaddr, NULL);
regards

thats two different change.
and apart from this:
1) the function declarations were renamed and moved from
lustre/include/linux/libcfs/libcfs.h to drivers/staging/lustre/include/linux/lnet/lib-lnet.h
2) some functions you have changed the coding style. like:
- rc = libcfs_sock_getaddr(conn->ksnc_sock, 0,
- &conn->ksnc_myipaddr, NULL);
+ rc = lnet_sock_getaddr(conn->ksnc_sock, 0, &conn->ksnc_myipaddr, NULL);
regards

Those are tiny related changes. They're fine. When you rename
functions you normally have to change the indenting as well.

* [lustre-devel] [PATCH v4 5/7] staging:lustre: use available kernel wrappers in lib-socket.c

Instead of handling calls to struct proto ourselves we can use
equivalent kernel wrappers. No wrapper exist for unlocked ioctl
handling so we create one here for our use. I expect some day
that function will be integrated into sock.c.
