💅 __mpt3sas_get_sdev_by_rphy — from the Kernel API Manual, bestie 🎀

okay so picture this: you're deep in the SCSI stack, everybody's yelling about rphys and sas_devices, and you just need one little lookup to go right. that's this function. she's a search function. she's lowkey iconic. let's get into it ✨

🌸 NAME 🌸

__mpt3sas_get_sdev_by_rphy — sas device search, fr fr 🔍

🦋 SYNOPSIS 🦋

struct _sas_device * __mpt3sas_get_sdev_by_rphy (struct MPT3SAS_ADAPTER
*ioc , struct sas_rphy *rphy );

like that's the whole summoning circle. give her the adapter, give her the rphy, she gives you back a struct _sas_device *. no cap. 💫

🎀 ARGUMENTS 🎀

  • ioc — the per adapter object. yes, per adapter, like each one has its own whole personality and you gotta hand over the right one 💖
  • rphy — a sas_rphy pointer. this is the thing you're searching from, bestie. she's your starting point 🧚

👑 CONTEXT 👑

okay this part matters, listen up: this function will acquire ioc->sas_device_lock, and it will release it before returning the sas_device object.

so like… the lock is handled for you, she's not gonna walk out the door still holding it 🙏 that's the whole vibe. don't go double-locking, don't panic, just trust her.

⭐ DESCRIPTION ⭐

she searches for the sas_device starting from the rphy object, then returns the sas_device object. that's it. that's the function. short, sweet, and absolutely serving ✨
