Are there others functions which i could use to > associate this file and a vmalloc'ed space ? As I said, you don't want to mmap a file in kernel memory. You only have 128 MB of vmalloc space and you don't want to waste it. If you know which addresses within the file you want to access, why don't you access them through the page cache functions ? regards, Rik -- Bravely reimplemented by the knights who say "NIH". http://www.surriel.com/ http://guru.conectiva.com/ Current spamtrap: october@surriel.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
