nfsd4_deleg_...pen_conflict(9)

NAME 🌸

okay so welcome to the nfsd4_deleg_...pen_conflict(9) page in the Kernel API Manual ✨ the actual function is nfsd4_deleg_lm_open_conflict — it checks if the given file points to an inode that has an existing open that would conflict with the desired lease. that's the whole assignment, bestie 💅

SYNOPSIS 🦋

int nfsd4_deleg_lm_open_conflict (struct file *filp , int arg );

ARGUMENTS 🎀

• filp — file to check. literally the file we're checking, no cap.
• arg — type of lease that we're trying to acquire. that's the lease vibe we want.

DESCRIPTION 🔥

The kernel will call into this operation to determine whether there are conflicting opens that may prevent the deleg from being granted. For nfsd, that check is done at a higher level, so this trivially returns 0. periodt — it's giving "nothing to see here, the grown-ups already checked" 💀✨
