But since a page can only be identified within a folio in case the page number is known (*) ITSM the tapset should simply keep probe nfs.aop.readpage(s) untouched, and provide brand new probe nfs.aop.readfolio. Attached trivial version of probe nfs.aop.readfolio. ------- * https://elixir.bootlin.com/linux/latest/source/include/linux/page-flags.h#L= 282 --=20 You are receiving this mail because: You are the assignee for the bug.=
