[PATCH 07/11] Docs/scsi: scsi-generic: multiple cleanups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Make the heading be concise yet still descriptive.
This makes the subsystem table of contents more readable (IMO).

Spell "CDROM" as "CD-ROM".
Capitalize "Linux".

Use https instead of http for URLs.

Drop the Linux Documenation Project URL for the SCSI generic HOWTO
since it hasn't been updated since 2002. Use Doug Gilbert's URL
for it instead.

Drop some outdated documentation & references.
