nfs4_put_state_owner(9)

Kernel API Manual, but make it group-chat: we’re talking nfs4_put_state_owner(9) today, bestie. 💅

🌸 NAME 🌸

nfs4_put_state_owner — Release a nfs4_state_owner

✨ SYNOPSIS ✨

void nfs4_put_state_owner (struct nfs4_state_owner *sp );

🎀 ARGUMENTS 🎀

• sp — state owner data to release.

🦋 DESCRIPTION 🦋

Okay so the important note: released state owners get kept on an LRU list. This is literally caching valid state owners so they can be reused, which avoids the OPEN_CONFIRM on minor version 0. It also pins the uniquifier of dropped state owners for a while, to ensure that those state owner names are never reused. No cap.
