Subject: Page size andFS blocksize
Date: Sat, 16 Nov 2002 23:03:20 -0800 (PST) [thread overview]
Message-ID: <20021117070320.75710.qmail@web12305.mail.yahoo.com> (raw)
Hi,
I was browsing the block device read/write code in fs/buffer.c (kernel
version 2.4.18).
>From waht I understood, there is an implicit assumption that
filesystem block sizes
are never more than the size of a single page. I say this because I
couldn't figure
out how to specify if the page being read is part of a block. (The
buffer_head structure
has no member that says 'offset within the block').
Have I read the code right, or am I missing something? And has this
changed in
2.5?
-Thanks,
Ravi.
