ibmvfc_tasklet(9)
πΈ ibmvfc_tasklet πΈ (Kernel API Manual, section 9)
okay bestie, welcome to the ibmvfc extended universe π this one's a tiny lil entry in the Kernel API Manual, but she's got lore. sit down, grab a strawberry drink π, and let's get into it.
β¨ NAME β¨
ibmvfc_tasklet β the interrupt handler tasklet π
like, that's the whole job title. she's a tasklet, she handles interrupts, she's booked and busy.
π¦ SYNOPSIS π¦
void ibmvfc_tasklet (void *data );
that's it. that's the whole signature. short, iconic, no notes π
π ARGUMENTS π
dataβ theibmvfchost struct π that's it, that's the argument. one (1) thing. she keeps it simple, unlike your group chat at 2am.
β RETURN β
Nothing. literally nothing. zero. void energy, no return value, she gives and gives and asks for nothing back π«Ά (well, she returns void, so, you know. nothing.)
π SEE ALSO π
okay so this is the part where the whole family shows up π and I mean the whole family. every single one of these is in the kernel file ./drivers/scsi/ibmvscsi/ibmvfc-core.c β no cap, that's the path, write it down.
here's the entire guest list, in order, no skips, no plus-ones:

like I said. the whole family π every auntie, every cousin, every __-prefixed sibling. iykyk.
no cap though β if you're looking for any of them, they live in ./drivers/scsi/ibmvscsi/ibmvfc-core.c. that's the address, don't @ me.
and that's the page, bestie π§ literally all of it. this lil writeup ships out of ./drivers/scsi/ibmvscsi, October 2026 edition β mwah, love that for us πβ¨ go forth and handle those interrupts responsibly π
