When attempting to establish a local ephemeral endpoint for a TCP or UDP socket, do not explicitly call bind, instead let it happen implicilty when the socket is first used. The main motivating factor for this change is when TCP runs out of unique ephemeral ports (i.e. cannot find any ephemeral ports which are not a part of *any* TCP connection). In this situation if you explicitly call bind, then the call will fail with EADDRINUSE. However, if you allow the allocation of an ephemeral port to happen implicitly as part of connect (or other functions), then ephemeral ports can be reused, so long as the combination of (local_ip, local_port, remote_ip, remote_port) is unique for TCP sockets on the system. This doesn't matter for UDP sockets, but it seemed easiest to treat TCP and UDP sockets the same. This can allow mount.nfs(8) to continue to function successfully, even in the face of misbehaving applications which are creating a large number of TCP connections.

filelayout_retry_commit was recently split out from alloc_ds_commits, but was done in such a way that the bucket pointer always starts at index 0 no matter what the @idx argument is set to. The intention of the @idx argument is to retry commits starting at bucket @idx. This is called when alloc_ds_commits fails for a bucket.

Most callers of that functions acqure the mutex by themselves and ufs_{new,free}_inode() do that via lock_ufs(), i.e we have an unavoidable double lock. The patch proposes to resolve the issue by making sure that ufs_{new,free}_inode() are not called with the mutex held. Found by Linux Driver Verification project (linuxtesting.org).

The update_walltime() code works on the shadow timekeeper to make the seqcount protected region as short as possible. But that update to the shadow timekeeper does not update all timekeeper fields because it's sufficient to do that once before it becomes life. One of these fields is tkr.base_mono. That stays stale in the shadow timekeeper unless an operation happens which copies the real timekeeper to the shadow. The update function is called after the update calls to vsyscall and pvclock. While not correct, it did not cause any problems because none of the invoked update functions used base_mono. commit cbcf2dd3 (x86: kvm: Make kvm_get_time_and_clockread() nanoseconds based) changed that in the kvm pvclock update function, so the stale mono_base value got used and caused kvm-clock to malfunction. Put the update where it belongs and fix the issue.

The function cleaning up an initialized event was called from the "event_del" handler, instead of being used as the "destroy" callback. In case of events group allocation this caused NULL pointer dereference (as events are added and deleted multiple times then). Fixed now.

Dave Hansen reports a massive scalability regression in an uncontained page fault benchmark with more than 30 concurrent threads, which he bisected down to 05b84301 ("mm: memcontrol: use root_mem_cgroup res_counter") and pin-pointed on res_counter spinlock contention. That change relied on the per-cpu charge caches to mostly swallow the res_counter costs, but it's apparent that the caches don't scale yet. Revert memcg back to bypassing res_counters on the root level in order to restore performance for uncontained workloads.

This patch changes sync_filesystem() to be EXPORT_SYMBOL(). The reason this is needed is that starting with 3.15 kernel, due to Theodore Ts'o's commit 02b9984d ("fs: push sync_filesystem() down to the file system's remount_fs()"), all file systems that have dirty data to be written out need to call sync_filesystem() from their ->remount_fs() method when remounting read-only. As this is now a generically required function rather than an internal only function it should be EXPORT_SYMBOL() so that all file systems can call it.
