π mpt3sas_raid_device_find_by_handle(9) π
okay so bestie, welcome to the Kernel API Manual β¨ β this one's a little lookup function from the mpt3sas driver and it's honestly so simple it's giving main character energy in its minimalism. Let's get into it π«Ά
πΈ NAME πΈ
mpt3sas_raid_device_find_by_handle β the raid device search. that's it, that's the whole vibe. you hand it a handle, it hands you a raid device. slay π₯
π SYNOPSIS π
struct _raid_device * mpt3sas_raid_device_find_by_handle (struct
MPT3SAS_ADAPTER *ioc , u16 handle );
π¦ ARGUMENTS π¦
iocβ the per adapter object, aka the whole controller's whole personality πhandleβ the sas device handle (assigned by firmware, so like, not your call, the firmware picked it, respect it π)
β οΈ CONTEXT β οΈ
the calling function should acquire ioc->raid_device_lock β no cap, this is not optional, bestie π lock it before you call it or things get messy.
π DESCRIPTION π
so what does it actually do? it searches for the raid_device based on the handle, then returns the raid_device object. literally that's it. a little find-and-return. lowkey iconic for how unbothered it is π
π SEE ALSO π
okay this is the part where it gets unhinged β the cross-reference list is long long. like, main-character-of-the-whole-source-file long. here's every single one, preserved in all its glory β¨

and that's the whole page, bestie π§ this little cutie lives in ./drivers/scsi/mpt3sas, dated October 2026, and the manual itself answers to the name mpt3sas_raid...nd_by_handle(9) β yes the header truncates it, no we don't know why, and honestly? we're not gonna ask π bye bye, go lock that raid_device_lock before you call anything π
