ext2's nobh mount option - what problem does it solve?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I'm unsure of the problem that ext2's nobh mount option solves. The man
page and code tersely states that it prevents 'attaching of
buffer_heads to pages'. But why is that A Bad Thing? What problems are
avoided by not using buffer_heads?

Thanks,
Kirk
