This patch tightens the read-only access checks in btrfs_permission to
match the constraints in inode_permission. Currently, even though the
device node itself will be unmodified, read-write access to device nodes
is denied to when the device node resides on a read-only subvolume or a
is a file that has been marked read-only by the btrfs conversion utility.
With this patch applied, the check only affects regular files,
directories, and symlinks. It also restructures the code a bit so that
we don't duplicate the MAY_WRITE check for both tests.

There was a problem with the parse_events() code not printing the
correct event name when an event was unknown and starting with an 'r'.
The source of the problem was the way raw notation was parsed.
Without the patch:
$ perf stat -e retired_foo
invalid event modifier: 'tired_foo'
With the patch:
$ perf stat -e retired_foo
invalid or unsupported event: 'retired_foo'
This also covers the case where the name of the event was not printed at
all when perf was linked with libpfm4.

When no event is given to perf record, perf top, a default event is
initialized (cycles). However, perf_evlist__add_default() was not
setting the symbolic name for the event. Perf top worked simply because
it was reconstructing the name from the event code. But it should not
have to do this. This patch initializes the evsel->name field properly.
This second version improves the code flow on the non error path.

Eduard Sinelnikov (eduard.sinelnikov@gmail.com) found that if we change
bonding mode from active backup to round robin, some slaves are still keeping
"backup", and won't transmit packets.
As Jay Vosburgh(fubar@us.ibm.com) pointed out that we can work around that by
removing the bond_is_active_slave() check, because the "backup" flag is only
meaningful for active backup mode.
But if we just simply ignore the bond_is_active_slave() check,
the transmission will work fine, but we can't maintain the correct value of
"backup" flag for each slaves, though it is meaningless for other mode than
active backup.
I'd like to reset "backup" and "inactive" flag in bond_open,
thus we can keep the correct value of them.
As for bond_is_active_slave(), I'd like to prepare another patch to handle it.
V2:
Use C style comment.
Move read_lock(&bond->curr_slave_lock).
Replace restore with reset, for active backup mode, it means "restore",
but for other modes, it means "reset".

The order-based approach is not only less efficient (requiring a shift
and a compare, typical generated code looking like this
mov eax, [machine_to_phys_order]
mov ecx, eax
shr ebx, cl
test ebx, ebx
jnz ...
whereas a direct check requires just a compare, like in
cmp ebx, [machine_to_phys_nr]
jae ...
), but also slightly dangerous in the 32-on-64 case - the element
address calculation can wrap if the next power of two boundary is
sufficiently far away from the actual upper limit of the table, and
hence can result in user space addresses being accessed (with it being
unknown what may actually be mapped there).
Additionally, the elimination of the mistaken use of fls() here (should
have been __fls()) fixes a latent issue on x86-64 that would trigger
if the code was run on a system with memory extending beyond the 44-bit
boundary.

The ASoC core tries to not enforce symmetric rates when
two streams open simultaneously. It does so by checking
rtd->rate being zero. This works exactly once after booting
because it is not set to zero again when the streams close.
Fix this by setting rtd->rate when no active stream is left.
[This leads to lots of warnings about not enforcing the symmetry in some
situations as there's a race in the userspace API where we know we've
got two applications but don't know what rates they want to set.
