These include: (1) Remove "inline" from the dummy cifs_proc_init/clean() functions as they are in a .c file. (2) Move should_compress()'s kdoc comment to the .c file and remove kdoc markers from the comments. (3) Rename CIFS_ALLOW_INSECURE_LEGACY in #endif comments to have CONFIG_ on the front to allow the script to recognise it. (4) Don't let comments have bare words at the left margin as that confused the simplistic function detection code in the script. (5) Adjust some argument lists so that when and if the cleanup script is run they don't end up over 100 chars. (6) Fix a few comments to have missing '*' added or the "*/" moved to their own lines so that checkpatch doesn't moan over the cleanup script patch. (7) Move struct cifs_calc_sig_ctx to cifsglob.h. (8) Remove some __KERNEL__ conditionals.
