* Remove in-source changelog. It's archived permanently in git and
various kernel archives, and changelogs should exist purely in git.
* Remove 2.4.x kernel support. It is an active obstacle to
modernizing this driver, at this point. This includes killing
gdth_kcompat.h which is 100% redundant in modern kernels.

Rather than having internal commands abuse scsi_done to call
gdth_scsi_done, have all the places that use to call scsi_done directly
call gdth_scsi_done, which now checks whether the command was internal,
and calls scsi_done if not.

- Drivers/transports that want to send a synchronous REQUEST_SENSE command
as part of their .queuecommand sequence, have 2 new API's that facilitate
in doing so and abstract them from scsi-ml internals.
void scsi_eh_prep_cmnd(struct scsi_cmnd *scmd,
struct scsi_eh_save *sesci, unsigned char *cmnd,
int cmnd_size, int sense_bytes)
Will hijack a command and prepare it for request sense if needed.
And will save any later needed info into a scsi_eh_save structure.
void scsi_eh_restore_cmnd(struct scsi_cmnd* scmd,
struct scsi_eh_save *sesci);
Will undo any changes done to a command by above function. Making
it ready for completion.
- Re-factor scsi_send_eh_cmnd() to use above APIs

- Support of cmnd==NULL in call to scsi_send_eh_cmnd()
- In the @sense_bytes case set transfer size to the minimum
size of sense_buffer and passed @sense_bytes. cmnd[4] is
set accordingly.
- REQUEST_SENSE is set into cmnd[0] so if @sense_bytes is
not Zero passed @cmnd should be NULL.
- Also save/restore resid of failed command.
- Adjust caller

Fix section mismatch in the Adaptec DPT SCSI Raid driver.
WARNING: vmlinux.o(.init.text+0x1fcd2): Section mismatch:
reference to .exit.text:adpt_exit (between 'adpt_init' and 'ahc_linux_init')
This warning is due to adaptec device detection calling the exit routine on
failure to properly register the adaptec device.
The exit routine + call was added on July 30 by
Commit: 55d9fcf57b
Author: Matthew Wilcox
Subject: [SCSI] dpt_i2o: convert to SCSI hotplug model.
Mathew: isn't a module exit routine a little too strong to be calling on the
failure of a single device? Module exit implies that other, non-failing
adaptec raid devices will also get shut down.

Modify ocfs2_dir_foreach_blk() to optionally return any error from the
filldir callback. This way ocfs2_dirforeach() can terminate early, as
opposed to always passing through the entire directory. This fixes a bug
introduced during a previous code refactor where ocfs2_empty_dir() would
loop infinitely.

Create all new directories with OCFS2_INLINE_DATA_FL and the inline data
bytes formatted as an empty directory. Inode size field reflects the actual
amount of inline data available, which makes searching for dirent space
very similar to the regular directory search.
Inline-data directories are automatically pushed out to extents on any
insert request which is too large for the available space.

This splits out extent based directory read support and implements
inline-data versions of those functions. All knowledge of inline-data versus
extent based directories is internalized. For lookups the code uses
ocfs2_find_entry_id(), full dir iterations make use of
ocfs2_dir_foreach_blk_id().

This fixes up write, truncate, mmap, and RESVSP/UNRESVP to understand inline
inode data.
For the most part, the changes to the core write code can be relied on to do
the heavy lifting. Any code calling ocfs2_write_begin (including shared
writeable mmap) can count on it doing the right thing with respect to
growing inline data to an extent tree.
Size reducing truncates, including UNRESVP can simply zero that portion of
the inode block being removed. Size increasing truncatesm, including RESVP
have to be a little bit smarter and grow the inode to an extent tree if
necessary.

This hooks up ocfs2_readpage() to populate a page with data from an inode
block. Direct IO reads from inline data are modified to fall back to
buffered I/O. Appropriate checks are also placed in the extent map code to
avoid reading an extent list when inline data might be stored.

Add the disk, network and memory structures needed to support data in inode.
Struct ocfs2_inline_data is defined and embedded in ocfs2_dinode for storing
inline data.
A new inode field, i_dyn_features, is added to facilitate tracking of
dynamic inode state. Since it will be used often, we want to mirror it on
ocfs2_inode_info, and transfer it via the meta data lvb.

ocfs2_rename() does direct manipulation of the dirent it's gotten back from
a directory search. Wrap this manipulation inside of a function so that we
can transparently change directory update behavior in the future. As an
added bonus, this gets rid of an ugly macro.

A couple paths which needed to just match a parent dir + name pair to an

We can preserve the behavior of ocfs2_empty_dir(), while getting rid of the

filldir_t can take this, so don't turn de->inode into a 32 bit value. Right
now this doesn't make a difference since no ocfs2 inodes overflow that, but
