This is a very early prototype of what i working on. I have done only minimal
testing of this. To use one need to use the below steps.
io_manager io_mng = stack_io_manager_init();
stack_push_io_manager(io_mng, unix_io_manager);
stack_push_io_manager(io_mng, undo_io_manager);

This I/O manager helps in stacking different I/O managers.
For example one can stack the undo I/O manager on top
of Unix I/O manager to achieve the undo functionality.

This I/O manager saves the contents of the location being overwritten
to a tdb database. This helps in undoing the changes done to the
file system.
This can be stacked over unix I/O manager to get the undo functionality.

This looks like it will have the same problem on s390 as
sys_sync_file_range. Maybe the prototype should be:
asmlinkage long sys_fallocate(loff_t offset, loff_t len, int fd, int mode)
Yes, but the trouble is that there was a contrary viewpoint preferring

Of course the interface used by an application program would have the
fd first. Glibc can do the translation.
I think that was understood.
OK, then what does it matter what the glibc/kernel interface is, as

Hi Valerie,
I tried the patches and while the tools such as mkfs and debugfs seem
to work fine, I am still unable to mount a filesystem with block

Hello all,
this is something I have long wondered about but have been afraid to ask.

Hi Jose,
I'm sorry to reply so late, I had a day off yesterday.
I only tested the tools on an x86_64 system. Could it be an endianess issue?
On which platform do you run?

I have the updated patches ready which take care of Andrew's comments.
Will run some tests and post them soon.
But, before submitting these patches, I think it will be better to finalize
on certain things which might be worth some discussion here:
1) Should the file size change when
