[PATCH v3 0/5] fbdev: Decouple deferred I/O from struct page

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Rework the fbdev deferred-I/O to not interfere with fields of struct
page. All references from deferred-I/O code to fields in struct page
are gone. The rsp state is help in a separate pageref structure.

v3:
	* rename pagelist to pagereflist (Sam)
	* use pageref->offset over page->index (Javier)
v2:
	* split off from a larger patchset [1]
