[PATCH v2] vhost/vsock: specify module version

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

 



Add an explicit MODULE_VERSION("0.0.1") specification for the vhost_vsock module.

It is useful because it allows userspace to check if vhost_vsock is there when it is
configured as a built-in.

This is what we have *without* this change and when vhost_vsock is configured
as a module and loaded:

$ ls -la /sys/module/vhost_vsock
total 0
drwxr-xr-x   5 root root    0 Sep 29 19:00 .
drwxr-xr-x 337 root root    0 Sep 29 18:59 ..
-r--r--r--   1 root root 4096 Sep 29 20:05 coresize
drwxr-xr-x   2 root root    0 Sep 29 20:05 holders
-r--r--r--   1 root root 4096 Sep 29 20:05 initsize
-r--r--r--   1 root root 4096 Sep 29 20:05 initstate
drwxr-xr-x   2 root root    0 Sep 29 20:05 notes
-r--r--r--   1 root root 4096 Sep 29 20:05 refcnt
drwxr-xr-x   2 root root    0 Sep 29 20:05 sections
-r--r--r--   1 root root 4096 Sep 29 20:05 srcversion
-r--r--r--   1 root root 4096 Sep 29 20:05 taint
--w-------   1 root root 4096 Sep 29 19:00 uevent

When vhost_vsock is configured as a built-in there is *no* /sys/module/vhost_vsock directory at all.
And this looks like an inconsistency.

With this change, when vhost_vsock is configured as a built-in we get:
$ ls -la /sys/module/vhost_vsock/
total 0
drwxr-xr-x   2 root root    0 Sep 26 15:59 .
drwxr-xr-x 100 root root    0 Sep 26 15:59 ..
--w-------   1 root root 4096 Sep 26 15:59 uevent
-r--r--r--   1 root root 4096 Sep 26 15:59 version
