The patch below introduces special thresholds to keep root node in the trie

Overall it seems to be gain and this was also proposed by one the authors
of the paper in recent a seminar.

the initial implementation of file truncation. Now both open(2)ing
a file with the O_TRUNC flag and the {,f}truncate(2) system calls
will resize a file appropriately. The limitations are that only
uncompressed and unencrypted files are supported. Also, there is
only very limited support for highly fragmented files (the ones whose
$DATA attribute is split into multiple attribute extents).

as an extra parameter. This is needed since we need to know the size
before we can map the mft record and our callers always know it. The
reason we cannot simply read the size from the vfs inode i_size is
that this is not necessarily uptodate. This happens when
ntfs_attr_make_non_resident() is called in the ->truncate call path.

This redoes the n_ports logic I proposed before as a bitmask.
ata_pci_init_native_mode is now used with a mask allowing for mixed mode
stuff later on. ata_pci_init_legacy_port is called with port number and
does one port now not two. Instead it is called twice by the ata init
logic which cleans both of them up.
There are stil limits in the original code left over
- IRQ/port mapping for legacy mode should be arch specific values
- You can have one legacy mode IDE adapter per PCI root bridge on some systems
- Doesn't handle mixed mode devices yet (but is now a lot closer to it)
Replicate IGMP frames across all slaves in activebackup mode. This
ensures fail-over is rapid for multicast traffic as well. Otherwise,
multicast traffic will be lost until the next IGMP membership report
poll timeout.
This is conceptually similar to the treatment of IGMP traffic in
bond_alb_xmit. In that case, IGMP traffic transmitted on any slave
is re-routed to the active slave in order to ensure that multicast
traffic continues to be directed to the active receiver.

Patch has been tested on IA64 platform with Xframe II adapter,

Unfortunately, [your patch] might address the crash but doesn't address
the real problem. It turns out that the problem is one of padding
(the firmware cksum engine works only on 32-bit chunks, yuck), so
the special casing for length == 1 wasn't sufficient anyway.
This patch addresses the issue, as well the other issue of i386 +
CONFIG_HIGHMEM being broken. It is pretty much the same workaround
that Adaptec themselves used in their Windows driver. I have yet to
check if it fixes the problem when the skb is non-linear, but this
patch _will_ solve the problem for 99% of the users out there (those
not using sendfile).
