Hi, > can anyone explain what is the difference between the gfp flags > GFP_KERNEL and GFP_USER, knowing the fact that both have the same > modifier flags (__GFP_WAIT | __GFP_IO | __GFPFS) > The __GFP_HARDWALL is the flag that makes the difference. #define GFP_KERNEL (__GFP_WAIT | __GFP_IO | __GFP_FS) #define GFP_USER (__GFP_WAIT | __GFP_IO | __GFP_FS | __GFP_HARDWALL) There seems to be some concept of hardwalls and softwalls, and it seems this flag reduces the softwall check to hardwall. Given limited knowledge of allocator ... this is all I can say :-( Rajat -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
