netfs_end_io_read(9)

💅 netfs_end_io_read — the Kernel API Manual, bestie edition 🎀

okay so this is a page from the Kernel API Manual, and honestly? it's short, it's sweet, and it's lowkey iconic for how much it does with so few words. let's get into it ✨

---

✨ NAME ✨

netfs_end_io_read — declare that the buffered read operation is done, fr fr 🫶

like, that's literally the whole job. you did the buffered read, now you're telling the kernel "yeah bestie, we're done here" 💖

---

✨ SYNOPSIS ✨

void netfs_end_io_read (struct inode *inode );

that's it. that's the whole call. no cap. 🌸

---

✨ DESCRIPTION ✨

so here's the vibe 💅 — you call netfs_end_io_read to declare that a buffered read operation is done, and it releases the shared lock on inode->i_rwsem.

think of it like this: you borrowed the shared lock when you started this whole buffered read situation (iykyk), and now you're handing it back. thank u, next. ✨ the lock gets released, everything's tidy, the kernel can breathe again. main character energy from start to finish, honestly 😭

bestie note: this is the end of the operation. if you skipped the matching start call, that's on you — the lock has to come from somewhere 👑 (check the SEE ALSO girlies below, one of them is your beginning 🔥)

---

✨ ARGUMENTS ✨

• inode — file inode. that's the file you were reading from, queen 🦋

✨ SEE ALSO ✨

and that's a wrap on this little page 🎀 it lives in ./fs/netfs, dated October 2026, and it's filed under the header netfs_end_io_read(9) in the Kernel API Manual — so if you ever forget where you found it, now you know 💖 slay, go release that shared lock, periodt 💅✨
