From: Paolo Abeni pabeni@redhat.com
[ Upstream commit 86730ac255b0497a272704de9a1df559f5d6602e ]
After the blamed commit below, if the MPC subflow is already in TCP_CLOSE status or has fallback to TCP at mptcp_disconnect() time, mptcp_do_fastclose() skips setting the `send_fastclose flag` and the later __mptcp_close_ssk() does not reset anymore the related subflow context.
Any later connection will be created with both the `request_mptcp` flag and the msk-level fallback status off (it is unconditionally cleared at MPTCP disconnect time), leading to a warning in subflow_data_ready():

commit 33cf66d88306663d16e4759e9d24766b0aaa2e17 upstream.
Add a randomized algorithm that runs newidle balancing proportional to its success rate.
This improves schbench significantly:
6.18-rc4: 2.22 Mrps/s 6.18-rc4+revert: 2.04 Mrps/s 6.18-rc4+revert+random: 2.18 Mrps/S
Conversely, per Adam Li this affects SpecJBB slightly, reducing it by 1%:
6.17: -6% 6.17+revert: 0% 6.17+revert+random: -1%

From: Mike Snitzer snitzer@kernel.org
commit 3af870aedbff10bfed220e280b57a405e972229f upstream.
Commit f2060bdc21d7 ("nfs/localio: add refcounting for each iocb IO associated with NFS pgio header") inadvertantly reintroduced the same potential for __put_cred() triggering BUG_ON(cred == current->cred) that commit 992203a1fba5 ("nfs/localio: restore creds before releasing pageio data") fixed.
Fix this by saving and restoring the cred around each {read,write}_iter call within the respective for loop of nfs_local_call_{read,write} using scoped_with_creds().
NOTE: this fix started by first reverting the following commits:
94afb627dfc2 ("nfs: use credential guards in nfs_local_call_read()") bff3c841f7bd ("nfs: use credential guards in nfs_local_call_write()") 1d18101a644e ("Merge tag 'kernel-6.19-rc1.cred' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs")
followed by narrowly fixing the cred lifetime issue by using scoped_with_creds(). In doing so, this commit's changes appear more extensive than they really are (as evidenced by comparing to v6.18's fs/nfs/localio.c).
