[pve-devel] [PATCH storage 0/2] cifs plugin - add options parameter

[Stefan Hrdlicka]

This adds the options parameter to the CIFS plugin.

check propertyList is common for all plugins and it is therefore
not possible to have options twice with different descriptions. This patch moves
the options property from NFSPlugin.pm to the Plugin.pm level. The options
parameter has the same use for NFS & CIFS so it shouldn't be confusing
that they share it.

Just style nits :), so you can add

after addressing them.

Style nit: could be a single line with post-if

Style nit: single-use variable that can be avoided by using
$scfg->{options} directly below.

Style nit: already pre-existing problem, but nowadays, we put each
argument on a single line once it gets too long.

Maybe add "Additional" and briefly mention that we set some options like
username, vers, etc. based on the other settings?

Reading the man page, cache=loose sounds rather dangerous! I'd rather
have the example use something that can't lead to data corruption in
some scenarios :S
