SubjectRe: 128 kbytes allocation limit for kmalloc?
* mailarch@archivum.info | 2005-09-27 19:40:32 [+0200]:

Yes, multiple kmalloc calls. You can implement your own memory managment
in top of it. For further informations: cat /proc/slabinfo

>When I allocate more than 128 kbytes with the kmalloc call, kmalloc returns NULL.

If you need one continues chunk of memory you must take vmalloc. But
note the performance penalty and some other disadvantages (dma, ...).
