Hi,
See https://www.kernel.org/doc/Documentation/CodingStyle, Chapter 7, “Centralized exiting of functions” for a rationale.
I saw some functions where the idea above seems fitting. But there had also been some code parts, like this from the sandbox, where it didn't made any sense to me.
Like in the lines 1012, 1055, 1098 and 1138 of sandbox.c where we could just also use a break statement to leave the while loops.
For the lines 1273, 1278, 1284, 1290 and 1296 of sandbox.c I could understand the use of goto, although it would also work with "else if" very well.
It had been just an idea to improve the code base, although only from my point of view as it seems :)
Then I just keep reading the source code to understand it and somtimes also contribute to it, I hope.
bye Hartmut
