Is there any inode flag (or anything equivalent) indicating that
writing that particular inode to the device failed because of an IO
error?
I couldn't find one or determine what am I supposed to do when that happens
TIA

If you delayed any update until after a sync it wouldn't be a sync
anymore, would it?

I see, so a subsequent sync, fsync or umount fail with
. What happens to these pages later on?
Does the memory manager attempt to write them again? Is the error
somehow signalled to anyone? Do filesystems try to relocate the data
from bad blocks of the device?

Can I try to bring your attention once more to the following issue:

r the first method, but the second would make life
easier for filesystems which can have pages consisting of both mapped
and reserved blocks.
Thank you very much for your reply, the whole thread has been well
worth reading.

? Would some other
part of kernel break if there was a bunch of buffers assigned to the
same spot on the disk?
On the other hand, if I understand buffer flags correctly, I need to
be able to emulate mapping of buffers to set them dirty, or em I
wrong?
Thanks for any insight or thoughts,

way? - Does metadata mean, in true kernel naming confusion
spirit, device pages/blocks?).
Can anyone tell me what the relationship exactly is and what one has
to be aware of when manipulating either of these?
Thank you very much in advance,

Thanks for your reply, I found the the following thing interesting on its own:

Thank you very much for your reply.

Hi,
I have problems understanding the purpose of different entries of
struc address_space_operations in 2.6 kernels:
1. What is bmap for and what is it supposed to do?
2. What is the difference between sync_page and write_page?
3. What exactly (fs independent) is the relation in between
write_p
time the memory is accessed. Don't know how to do that or if you
would need to be platform specific, though.
