flush_dcache_page()

["Adil Mujeeb" <mujeeb.adil@xxxxxxxxx>]

Hi List,

 

I was going through the kernel source 2.6.16 and i came across the function call flush_dcache_page() inside function generic_file_buffered_write() (mm/filemap.c).

It is defined as :

 

#define flush_dcache_page(page)                 do { } while (0)
in file include/asm-i386/cacheflush.h

 

Does it solve any purpose?

 

Rgds,

Adil
