hi, all
as I understand, ->readpage() will be invoked on address space object at some point when you do a syscall on read.
for ext3, it will be ext3_readpage, which ask mpage_readpage() to do the job.
what I don't follow is why the function doc right before mapge_readpage() claims "This isn't called much at all".
is this not on the primary read I/O path anymore?
thanks
