skb_frag_page_copy(9)
π skb_frag_page_copy(9) β Kernel API Manual π
okay bestie, welcome to skb_frag_page_copy, straight out of the Kernel API Manual. it's a tiny little function, ngl β like, one job, does it, dips β but it's iconic in its own lowkey way and you're gonna understand it in like thirty seconds. periodt. β¨
πΈ NAME πΈ
skb_frag_page_copy β sets the page in a fragment from another fragment π«
that's it. that's the whole vibe. one fragment copies the page out of another fragment. no cap. π«Ά
π¦ SYNOPSIS π¦
void skb_frag_page_copy (skb_frag_t *fragto , const skb_frag_t *fragfrom );
notice the void β this one does not hand you anything back, she's a doer, not a returner. π
(also yes, the spacing in the original is exactly like that, we do not touch the code, bestie, we respect the code.)
β¨ ARGUMENTS β¨
fragtoβ the skb fragment where the page is set. this is the destination diva π β she's the one getting the page tucked into her.fragfromβ the skb fragment the page is copied from. this is the source, and she'sconst, so she stays untouched and unbothered π β main character energy, but respectful.
so like: page lives in fragfrom, page ends up set in fragto. two fragments, one copy. easy. π
π₯ SEE ALSO π₯
okay this is the part where the manpage goes feral β the SEE ALSO list is genuinely enormous, so buckle up, we're listing every single one because we do not skip β¨

likeβ¦ she's thriving in the skb cinematic universe fr fr π
lowkey reminder bestie: this page tells you it sets the page in one fragment from another fragment. that's the whole documented contract β don't go inventing extra behaviour for her, she's got enough going on π
mwah π that's the page! source: ./include/linux, dated October 2026, and you just read skb_frag_page_copy(9) from the Kernel API Manual. go copy a page, bestie, slay. π
