Re: [PATCH 10/19] readahead: state based method

Eric Dumazet a écrit :

Hum... This sizeof(struct file) increase seems quite large...

Have you ever considered to change struct file so that file_ra_state is not embedded, but dynamically allocated (or other strategy) for regular files ?

I mean, sockets, pipes cannot readahead... And some machines use far more sockets than regular files.

I wrote such a patch in the past I could resend...
