MEMFD_LUO_FOLIO_UPTODATE(9)
π MEMFD_LUO_FOLIO_UPTODATE β the folio is up-to-date, bestie
okay so real talk, this is a page straight out of the Kernel API Manual (memfd_luo_folio_uptodate(9), section 9, kernel API vibes only) and it's honestly short and sweet β a whole little flag with main character energy β¨
β¨ SYNOPSIS β¨
MEMFD_LUO_FOLIO_UPTODATE
no args, no flags, no drama β it's just the thing itself π
πΈ DESCRIPTION πΈ
so an up-to-date folio is one that's been zeroed out already, periodt. shmem zeroes out folios on first use (like, first touch = instant glaze of zeros), and this flag is the little bookkeeping sticker that tracks which folios still need that zeroing treatment π₯
think of it as the "bestie, this one's already handled π " marker. no cap.
