As I see it, the advantages are that we would a) match the
documentation (man pages & posix/SUS) which makes things easier for
application writers who won't have to scratch their beards wondering
why Linux doesn't behave like the docs say. And b) Linux behaviour
would match what most (all?) other Unices do, so there'll be less
hassle/bugs when porting apps from other systems to Linux. To me,
those look like significant bennefits.
As for the "it may break programs" bit, that of course is a concern,
but one way around that would be to stick it in -mm and let it cook
for a few kernel releases. Say we stick it in -mm with a plan to merge
it into 2.6.16-rc1, that should give it quite a bit of time to
determine if it breaks apps (and if it does, to fix those apps).
Just my 0.02euro.
