💫 sas_rphy_initialize(9) 💫

ok so this is a page from the Kernel API Manual (section 9, the kernel-functions girlies) and it's all about sas_rphy_initialize — literally the "common rphy initialization" moment. yes bestie, it's as iconic as it sounds 🎀

✨ NAME ✨

sas_rphy_initialize — common rphy initialization. that's it, that's the vibe 🦋

🌸 SYNOPSIS 🌸

void sas_rphy_initialize (struct sas_rphy *rphy );

no cap, it's a void function. it returns nothing. it simply does the thing and leaves. main character energy fr 💅

🎀 ARGUMENTS 🎀

  • rphy — the rphy you want to initialise. that's the whole assignment bestie, hand it over and it gets initialised 💖

🧚 DESCRIPTION 🧚

okay so picture this: two different allocator functions both need the exact same shared setup done for the rphy part, and instead of copy-pasting it (unhinged behaviour), they both call this one. the two functions are sas_end_device_alloc and sas_expander_alloc, and what they're doing is initialising the common rphy component that each of them has. lowkey the communal glue of the whole thing 🫶

same code for both, no duplication, everyone slays. periodt.

👑 SEE ALSO 👑

this is where it gets good — the whole friend group is listed, and it lives in the kernel file ./drivers/scsi/scsi_transport_sas.c. go say hi to:

like, the entire roster. iykyk 😭🔥

ngl there are no options, no exit statuses, no environment variables and absolutely zero warnings on this page — it's a clean, wholesome little function. cherish her 🙈

🌈 that's the whole page bestie! this one ships from ./drivers/scsi and it's dated October 2026 — so mark your calendar, mwah 💜⭐
