This has been resulting in a BUT_ON(ret) after btrfs_reserve_extent in
btrfs_cow_file_range. The reason is we don't actually calculate the bytes_super
for a block group until we go to cache it, which means that the space_info can
hand out reservations for space that it doesn't actually have, and we can run
out of data space. This is also a problem if you are using space caching since
we don't ever calculate bytes_super for the block groups. So instead everytime
we read a block group call exclude_super_stripes, which calculates the
bytes_super for the block group so it can be left out of the space_info. Then
whenever caching completes we just call free_excluded_extents so that the super
excluded extents are freed up. Also if we are unmounting and we hit any block
groups that haven't been cached we still need to call free_excluded_extents to
make sure things are cleaned up properly. Thanks,

When we're cleaning up the tree log we need to be able to remove free space from
the block group. The problem is if that free space spans bitmaps we would not
find the space since we're looking for too many bytes. So make sure the amount
of bytes we search for is limited to either the number of bytes we want, or the
number of bytes left in the bitmap. This was tested by a user who was hitting
the BUG() after search_bitmap. With this patch he can now mount his fs.

Since checkin ebba638ae7 we call
verify_cpu even in 32-bit mode. Unfortunately, calling a function
means using the stack, and the stack pointer was not initialized in
the 32-bit setup code! This code initializes the stack pointer, and
simplifies the interface slightly since it is easier to rely on just a
pointer value rather than a descriptor; we need to have different
values for the segment register anyway.
This retains start_stack as a virtual address, even though a physical
address would be more convenient for 32 bits; the 64-bit code wants
the other way around...

When the socket to the server is disconnected, the client more or less
immediately calls cifs_reconnect to reconnect the socket. The NegProt
and SessSetup however are not done until an actual call needs to be
made.
With the addition of the SMB echo code, it's possible that the server
will initiate a disconnect on an idle socket. The client will then
reconnect the socket but no NegotiateProtocol request is done. The
SMBEcho workqueue job will then eventually pop, and an SMBEcho will be
sent on the socket. The server will then reject it since no NegProt was
done.
The ideal fix would be to either have the socket not be reconnected
until we plan to use it, or to immediately do a NegProt when the
reconnect occurs. The code is not structured for this however. For now
we must just settle for not sending any echoes until the NegProt is
done.

This is due to the missing include of linux/usb/composite.h - this patch
adds the missing include.
In addition there's also a problem in fsg_common_init() where we memset
'common', but we use the size of a pointer to 'struct fsg_common' as the
size argument to memset(), not the actual size of the struct. This patch
fixes the sizeof so we zero the entire struct as intended.

Some experiment-based action to prevent my 8168 chipsets locking-up hard
in the irq handler under load (pktgen ~1Mpps). Apparently a reset is not
always mandatory (is it at all ?).
- RTL_GIGA_MAC_VER_12
- RTL_GIGA_MAC_VER_25
Missed ~55% packets. Note:
- this is an old SiS 965L motherboard
- the 8168 chipset emits (lots of) control frames towards the sender
- RTL_GIGA_MAC_VER_26
The chipset does not go into a frenzy of mac control pause when it
crashes yet but it can still be crashed. It needs more work.
