Description Kirill Stepanchuk 2009-06-15 22:10:06 UTC
Here is a patch to allow the sysctl interface to export byte values properly. This is sometimes needed if certain hardware needs to store a value as a byte in a struct. The sysctl interface would assume that the value is an 'int', with extraneous bits coming from neighbouring fields. This change adds a byte handler that internally converts unsigned bytes to ints, and then exports them to sysctl like a regular unsigned integer.

Fix: Patch attached with submission follows:
