Subject: How to filter the Block I/O in 2.6 kernel?
Date: Wed, 21 May 2008 12:05:30 +0800 [thread overview]
Message-ID: <6f4bf7350805202105g2594d85dt1ae3b650e3e3671@mail.gmail.com> (raw)
How to filter the Block I/O in 2.6 kernel?
I have looked some in blktrace.
blktrace can trace the block device I/O info. But that can't
filter/change this I/O.
Is the Linux kernel have any way to filter/change a block i/o before
it write to hard disk?
I don't want to change kernel code and re-build. Is Kernel already
have any I/O filter interface?
Thanks,
Xiongjia Le
