Just use kobject_set_name(), that works in all kernels (I think...).
Kernels newer than 2.6.23 currently fail with:

endio handling is typically called with interrupts disabled, but can
also be called with it enabled. So save interrupts before using KM_IRQ0
to be completely safe.

It now returns void and it is never called for partial completions, so
the bio->bi_size check must go.

This allows us to defrag huge directories, but skip the expensive defrag
case in more common usage, where it does not help as much.

I think check whether extent is a hole before update 'inode->i_blocks'
is unconditional required. (original codes check it only when
del_item isn't equal to 0)

found_type has already been decreased by codes above the change, I
think decrease it by one again doesn't make sense.

find_free_extent would fail to wrap around to the start of the drive because
it was doing the enospc case checking twice in some cases, causing it
to return -ENOSPC early.

btrfs_btree_balance_dirty is changed to pass the number of pages dirtied
for more accurate dirty throttling. This lets the VM make better decisions
about when to force some writeback.

The -ffunction-sections puts each text in .text.function_name section.
Without this patch, most functions are placed outside _text..._etext
area and it breaks show_stacktrace(), etc.

Use unsigned loads to avoid possible misscalculation of IP checksums. This
bug was instruced in f761106cd728bcf65b7fe161b10221ee00cf7132 (lmo) /
ed99e2bc1d (kernel.org).
[Original fix by Atsushi. Improved instruction scheduling and fix for
unaligned unsigned load by me -- Ralf]
