seq_has_overflowed(9)

💅 seq_has_overflowed(9) 💅

okay so this lil page is from the Kernel API Manual, and it's here to explain seq_has_overflowed — the glow-up check for whether a seq_file buffer went overboard. bestie, it's giving "did this thing overflow or not" energy, and we're gonna read it together. 🫶

✨ NAME ✨

seq_has_overflowed — check if the buffer has overflowed. that's the whole assignment, no cap. 💖

---

🌸 SYNOPSIS 🌸

bool seq_has_overflowed (struct seq_file *m );

---

🎀 ARGUMENTS 🎀

• m — the seq_file handle. that's it, that's the argument, she's iconic and singular. 💅

---

💖 DESCRIPTION 💖

so seq_files have a buffer, and that buffer may overflow. when this happens, a larger buffer is reallocated and all the data will be printed again. yes bestie, we re-run the printing era. 😭✨

the overflow state is true when m->count == m->size. literally that equality is the vibe check. 🦋

Returns true if the buffer received more than it can hold. periodt. 🌈

later, bestie 🫶 this cutie came from ./include/linux, stamped October 2026, and it's the seq_has_overflowed(9) page. mwah 💋
