I am going through and exploring/changing/testing everything to deal with GregKH/jmorris wanting a single xattr_gs_args structure reference where the flags argument is stowed, rather than YA adding a flags argument. It is doubling the (mechanical) codebase impact but decreases the future maintenance and _large_ set of stakeholders (+75 at last count). -- Mark On Fri, Aug 16, 2019 at 8:11 AM Jan Kara wrote: > On Thu 15-08-19 08:49:58, Mark Salyzyn wrote: > > Add a flag option to get xattr method that could have a bit flag of > > XATTR_NOSECURITY passed to it.

I will redo the manual audit, perhaps I need to not be so = scared of allconfig=C2=A0build ;-} (currently my runtime & buildtime te= st platform is android 4.19 kernel, my bad).

I am going= =C2=A0through and exploring/changing/testing everything to deal with GregKH= /jmorris wanting a single xattr_gs_args structure reference where the flags= argument is stowed, rather than YA adding a flags argument. It is doubling= the (mechanical) codebase impact but decreases the future maintenance and = _large_ set of stakeholders (+75 at last count).

The patch looks good to me. I can see you've missed conversion of one p= lace
in ext2 which 0-day spotted so that will need fixing. Otherwise feel free to add:
