💫 ib_inc_rkey(9) 💫

okay so bestie, welcome to the Kernel API Manual, and buckle up because today we're looking at one tiny little helper that does exactly one tiny little thing, and it does it immaculately. no notes. 🎀

✨ NAME ✨

ib_inc_rkey — increments the key portion of the given rkey. Can be used for calculating a new rkey for type 2 memory windows.

that's it. that's the whole job. it increments a key. she's an icon, she's a specialist, she's not trying to be everything. 💅

🌸 SYNOPSIS 🌸

u32 ib_inc_rkey (u32 rkey );

literally one function, one argument, one return value. lowkey the cleanest signature i've ever seen. 🦋

🫶 ARGUMENTS 🫶

  • rkey — the rkey to increment. that's the one, bestie. that's the one you're bumping up. ✨

🔥 SEE ALSO 🔥

okay so this is the part where the manpage goes absolutely feral and lists, like, the entire RDMA subsystem. no cap. i'm not skipping a single one, because every single one of these is part of the family. 🌈

first up, the kernel file:

./include/rdma/ib_verbs.h

then the whole squad:

like. ninety-something entries. she said "i contain multitudes" and meant it. 👑💀

💖 reminder bestie: ib_inc_rkey bumps the key portion of the rkey you hand it, and it's the move for calculating a new rkey for type 2 memory windows. that's the whole vibe. iykyk.

mwah, that's the page! 🍓 this little drop of wisdom came to you from the kernel file <code>./include/rdma</code>, dated October 2026 — go forth and increment responsibly, bestie. 💜✨
