I am fine with basically any decision as long as there's a single naming
convention, *except* for this part. Dashes in source files creates
confusion for module naming. Separators should be underscores. This is
a standing pet-peeve of mine, and while I certainly can't fix it
universally in the kernel, we can at least avoid creating an entire
subsystem that gets this wrong for all modules. :)
To illustrate:
$ modinfo dvb-bt8xx
filename: .../kernel/drivers/media/pci/bt8xx/dvb-bt8xx.ko
...
name: dvb_bt8xx
^ does not match the .ko file, nor source.
Primarily my issue is the disconnect between "dmesg" output and finding
the source. It's not like, a huge deal, but it bugs me. :) As in:
$ strings drivers/media/pci/bt8xx/dvb-bt8xx.o | grep 'Init Error'
4dvb_bt8xx: or51211: Init Error - Can't Reset DVR (%i)
All this said, if there really is some good reason to use dashes, I will
get over it. :P
(And now that I've had to say all this "out loud", I wonder if maybe I
could actually fix this all at the root cause: KBUILD_MOD_NAME... it is
sometimes used for identifiers, which is why it does the underscore
replacement... I wonder if it could be split into "name" and
"identifier"...)
