[uml-devel] Could you explain this strange fix?

[BlaisorBlade <bla...@ya...>]

This hunk comes straight from 2.4.24-3um. Could you explain it? Are you sure 
it's safe? Several people complain about patches later than 2.4.24-1 (even 
for stability), so I have doubts about it. Also, could you say me which is 
the fix for the "tracing myself" bug of 2.4? The patch is in 2.4.24-2, but 
since I've split it out, I cannot find which is the needed fix.
