Hi,
I've forgot to add the following two patches which should help to
identify explicit GFP_NO{FS,IO} usage from withing a scope context. Such
a usage can be changed to the full GFP_KERNEL because all the calls
from within the NO{FS,IO} scope will drop the __GFP_FS resp. __GFP_IO
automatically and if the function is called outside of the scope then
we do not need to restrict it to NOFS/NOIO as long as all the reclaim
recursion unsafe contexts are marked properly. This means that each
such a reported allocation site has to be checked before converted.
The debugging has to be enabled explicitly by a kernel command line
parameter and then it reports the stack trace of the allocation and
also the function which has started the current scope.
These two patches are _not_ intended to be merged and they are only
aimed at debugging.
