β¨ trace_block_rq_remap(9) β¨
okay so bestie, welcome to the Kernel API Manual π this little cutie lives in the kernel tracing world and honestly? she's giving backstage-pass energy π
πΈ NAME πΈ
trace_block_rq_remap β literally the tracepoint that maps a request for a block operation request π¦
β¨ SYNOPSIS β¨
void trace_block_rq_remap (struct request *rq , dev_t dev , sector_t
from );
no cap, that's the whole signature β she takes three things and returns void π
π ARGUMENTS π
rqβ the block IO operation request, aka the main character of this whole situation πdevβ the device for the operation, like which stage this performance is happening on πfromβ the original sector for the operation, the before pic basically π
π DESCRIPTION π
So here's the tea π: the block operation request rq in q has been remapped. That's it, that's the vibe.
The block operation request rq holds the current information, and from holds the original sector β so you get the now and the then, both slaying in the same call π«

ngl bestie, q shows up in the description without getting its own argument slot β that's just how the original text rolls, so I'm passing the message along exactly as written π«Ά
