I agree too.

Moreover, Hin-Tak asks about dprint() but not printk(). The dprint()
messages can be useful for debugging purposes and will be disabled for
usual kernel build.

I think that adding dprint() messages in hfs_find_init() is not
necessary. But adding dprint() for __hfsplus_ext_write_extent() and
other places can be useful, from my point of view. And such messages can
be useful as for HFS+ as for HFS drivers.

With the best regards,
Vyacheslav Dubeyko.
