• count — read bytes in this execution 📖 the actual number of bytes read this time around
• flags — used to set task->tk_flags in rpc_init_task function 🚩

💀 DESCRIPTION 💀

okay bestie, sit down, because this is the sad part 😭

All the nfs.proc.read kernel functions were removed in kernel commit 8e0969 in December 2006.

so these probes do not exist on Linux 2.6.21 and newer kernels.

fr fr. if you're on anything modern, this probe is giving ghost energy 👻 it's not there. it's not coming back. the kernel said "not me" and moved on. 💀

like, imagine the most iconic probe and then imagine it got deleted before some of us were even born. that's this one. tragic. but now you know, and knowing is the whole point 🎀
