d0547fe613 scst/scst_vdisk: Made error handling in bi_end_io function IRQ-safe since 
bi_end_io functions must be IRQ-safe.

A quote from a discussion between Alan Cox, Mikulas Patocka and Jens Axboe
(http://lkml.org/lkml/2008/7/2/69):

> >Right, that wont work of course. Completions are typically done through
> >a softirq, so it is not currently done with hard interrupts disabled.
> 
> I thought, from hardirq - that's what IDE is doing. And they are called 
> with interrupts disabled (maybe unless you specify unmaskirq, which is not 
> default). What block driver does completions with softirq? ... and why?

The key word is 'typically', the old IDE driver really isn't used very
much. The SCSI layer and eg cciss uses the block layer softirq
completions, so that is what 99% of the uses will be.

The patch itself was provided by Arne Redlich.

f9ca99c4da This patch simplifies the SCST sysfs code a little bit by 
introducing the functions sysfs_create_files() and sysfs_remove_files().
These functions have been introduced in kernel 2.6.34 via commit
1c205ae18db53ff72985dd79f3baaf2dbaba6db7. An implementation of these
functions has been included for older kernels.

b330889bf4 This patch fixes a class of race conditions in the ..._sysfs_del() 
functions: the kobject_put() calls should come after all kobject_del() calls
because as long as the last kobject_del() call hasn't been invoked, a sysfs
.show() or .store() callback may still be in progress that needs one of
these kobjects.

515fda68cf This patch simplifies the string duplication code in 
scst_sysfs.c and scst_vdisk.c. Code for duplicating '\0'-terminated
strings has been replaced by a call to kstrdup() and code for
duplicating fixed-length strings has been replaced by a call to
kasprintf(GFP_KERNEL, "%.*s", (int)size, buf).

649fef691e Changes to make fcst work on Linux 2.6.36. 
The biggest difference is that libfc no longer allocates a sequence
and exchange for incoming requests, and that eliminates a parameter
on the receive function.  This was done to help performance and
might help on short reads sometime in the future.

This also fixes an error in ft_send_read_data() that exceeds the
skb's SG list length limit on long reads when the NIC
supports large send offload.

I also made other minor changes like adding debugging.

ac5618b07e Adding patches for 2.6.36. These are similar to the 2.6.35 patches 
except for line number changes and a few interface changes imposed
by differences in libfc between 2.6.35 and 2.6.36, mostly due to the
change which doesn't allocate an exchange and sequence for incoming
requests.

ff7a986329 Add an fcoe patch for 2.6.35 to not deliver frames to fcst from softirq level. 
I believe this was causing a race leading to a WARN in fc_seq_send that
the sequence initiative wasn't held in ft_send_response().  It also caused
a problem for tcm_fc.
