Hi All,
I recently read that all fs codes actually do I/O to and from the
pagecache and then the dirty pages are synced to the disk later using
the bdflush daemon.This approach has some performance problems when I/O
is done thru write calls rather than mmap. I was just curious whether
this path was modified when XFS was written ( ie how cud such a approach
even work in case of jounalled file system when log operations are
needed bfore the data gets written out).
I am kinda newbie into kernel hacking and so i am sorry if my question
sounds dumb.
Cheers,
Arun.
