ceph_mdsc_wait_for_reset(9)

💅 ceph_mdsc_wait_for_reset — the kernel API manual, bestie edition

okay so real talk, this is the manpage for ceph_mdsc_wait_for_reset from the Kernel API Manual, and it is exactly what it says on the tin: you sit there and wait for a reset that's already in progress to finish. no cap. let's get into it 🎀

---

✨ NAME ✨

ceph_mdsc_wait_for_reset — wait for an active reset to complete 🦋

---

🌸 SYNOPSIS 🌸

int ceph_mdsc_wait_for_reset (struct ceph_mds_client *mdsc );

---

🫶 ARGUMENTS 🫶

• mdsc — the MDS client. that's it, that's the whole vibe 💖

---

🔥 DESCRIPTION 🔥

bestie, the return value is the whole personality here, so let's go one by one 👑

• Returns 0 if the reset completed successfully or if there was literally no reset active. slay, nothing to worry about 💅
• Returns -EAGAIN if the reset completed but it came back with an error — that's your cue, caller, go retry 🔁
• oh and important: the internal error (like -ENOMEM) is not propagated, because callers like open or flock have genuinely no way to act on work-function internals. like, what are they supposed to do with that? 😭 so the detailed error is available via debugfs reset/status and tracepoints instead — iykyk 🔍
• Returns -ETIMEDOUT if we timed out waiting. yeah. we waited too long. ⏰
• Returns -ERESTARTSYS if we got interrupted by a signal. rude but okay 🙈

fr fr, don't go looking for -ENOMEM in the return value — it lives in debugfs reset/status and tracepoints, not here. periodt.
