      drm/i915: Fix object refcount leak on mmappable size limit error path. · 14660ccd
      由 Eric Anholt 提交于 
      I've been seeing memory leaks on my system in the form of large
(300-400MB) GEM objects created by now-dead processes laying around
clogging up memory.  I usually notice when it gets to about 1.2GB of
them.  Hopefully this clears up the issue, but I just found this bug
by inspection.

      agp: iommu_gfx_mapped only available if CONFIG_INTEL_IOMMU is set · a08185a3
      由 Keith Packard 提交于 
      Kernels with no iommu support cannot ever need the Ironlake
work-around, so never enable it in that case.

Might be better to completely remove the work-around from the kernel
in this case?

like naming it after an extinct animal that just happened to be in the

      VFS: we need to set LOOKUP_JUMPED on mountpoint crossing · a3fbbde7
      由 Al Viro 提交于 
      Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.

Simple way to reproduce the problem in mainline:

    cat >/tmp/a.c <<'EOF'
    #include <unistd.h>
    #include <fcntl.h>
    #include <stdio.h>
    main()
    {
            struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
            if (fcntl(0, F_SETLK, &fl))
                    perror("setlk");
    }
    EOF
    cc /tmp/a.c -o /tmp/test

then on nfs4:

    mount --bind file1 file2
    /tmp/test < file1		# ok
    /tmp/test < file2		# spews "setlk: No locks available"...

What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.

The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks.  I.e.  set LOOKUP_JUMPED...
