Hi, I have posted the previous version here [1]. There are no real changes in the implementation since then. I've just added "lockdep: teach lockdep about memalloc_noio_save" from Nikolay which is a lockdep bugfix developed independently but "mm: introduce memalloc_nofs_{save,restore} API" depends on it so I added it here. Then I've rebased the series on top of 4.11-rc1 which contains sched.h split up which required to add sched/mm.h include. There didn't seem to be any real objections and so I think we should go and finally merge this - ideally in this release cycle as it doesn't really introduce any functional changes. Those were separated out and will be posted later. The risk of regressions should really be small because we do not remove any real GFP_NOFS users yet.
