Subject: [PATCH 0/2] ocfs2: Replace strlcpy with strscpy

Hi,

The main patch this series is targeting is [PATCH 2] which replaces
strlcpy() call with strscpy(). However, while I was tinkering through
the code I noticed that `module_param_call` is marked obsolete and
`module_param_cb` is preferred instead. So I have included [PATCH 1]
which does that.

A crucial thing in [PATCH 2] I would like to bring to reviewer's
attention is that it changes behavior for the case where
sizeof(@buffer) < DLMFS_CAPABILITIES. Currently, this is silently ignored
but with the current change it returns -errno.

Thanks,
Azeem
