Especially when changes are backported that seems to be a much better indicator of what is affected than some arbitrary kernel number. I have included a Fixes tags for the originally buggy commit and a Fixes tag for the incomplete fix for the originally buggy commit. As a rule I only include a kernel version number if the originally affected kernel is not in Linus's git tree, and not in Thomas's conversion of the original bitkeeper tree to git. > > - Sedat - > >> Reported-by: Andrei Vagin >> Tested-by: Andrei Vagin >> Fixes: ace0c791e6c3 ("proc/sysctl: Don't grab i_lock under sysctl_lock.") >> Fixes: d6cffbbe9a7e ("proc/sysctl: prune stale dentries during unregistering") >> Signed-off-by: "Eric W.
