In btrfs_ioctl_get_subvol_info(), there is a classic case where kzalloc()
was incorrectly paired with kzfree(). According to David Sterba, there
isn't any sensitive information in the subvol_info that needs to be
cleared before freeing. So kzfree() isn't really needed, use kfree()
instead.
I don't think this patch is necessary for any stable tree, it's meant
only to ease merging a tree-wide patchset to rename kzfree. In btrfs
code there was no point using it so it's plain kfree.
I've dropped it, thanks!
