Hi Linus - The following changes since commit 2d5404caa8c7bb5c4e0435f94b28834ae5456623: Linux 6.12-rc7 (2024-11-10 14:19:35 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git tags/nfsd-6.13 for you to fetch changes up to 583772eec7b0096516a8ee8b1cc31401894f1e3a: nfsd: allow for up to 32 callback session slots (2024-11-18 20:23:13 -0500) ---------------------------------------------------------------- NFSD 6.13 Release Notes Jeff Layton contributed a scalability improvement to NFSD's NFSv4 backchannel session implementation. This improvement is intended to increase the rate at which NFSD can safely recall NFSv4 delegations from clients, to avoid the need to revoke them. Revoking requires a slow state recovery process. A wide variety of bug fixes and other incremental improvements make up the bulk of commits in this series. As always I am grateful to the NFSD contributors, reviewers, testers, and bug reporters who participated during this cycle. ---------------------------------------------------------------- Al Viro
