smb2_flush(9)

smb2_flush(9) — Kernel API Manual energy ✨

hey bestie, welcome to the smb2_flush(9) page from the Kernel API Manual. This one is short, cute, and extremely on brand: it’s the handler for smb2 flush file - fsync. 💅

💖 NAME 💖

smb2_flush — handler for smb2 flush file - fsync.

That’s literally the whole name. She handles the smb2 flush file, and yes, fsync is right there in the description, periodt.

🌸 SYNOPSIS 🌸

int smb2_flush (struct ksmbd_work *work );

No cap, that’s the signature. One struct ksmbd_work * and we’re out. ✨

🦋 ARGUMENTS 🦋

• work — smb work containing flush command buffer. That’s the one thing you pass in, bestie.

💜 RETURN 💜

• 0 on success, otherwise error.

Zero means slay. Anything else means something went nope. 😭

🎀 SEE ALSO 🎀

The page points at the kernel file ./fs/smb/server/smb2pdu.c, and then it name-drops the whole squad. Full roll call, because nobody gets left on read:
