Hi!

It seems this is a general problem, but mostly on the application
side. See for example:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=147938

which shows that the application code uses the wrong type
for an ioctl argument.

It looks like it's an application error. So maybe upstream (CommVault)
can comment on this ?
