    SubjectRe: kmalloc: 56 is the answer to Linux, the Universe and Everything

    (I'm lazy at quoting....) This looks to be interesting:

    no. requests size requested
    24205 56 struct vm_area_struct
    303 988 struct task_struct
    303 84 struct mm_struct
    303 516 struct signal_struct
    303 16 struct fs_struct
    303 1060 struct files_struct
    211 96
    211 19
    139 160
    [ descends into noise]

    I only went through the 'easy' requests - those with 303 requests.
    They come from creating new tasks, but all of the structures are
    allocated seperately. I decreased NR_OPEN on my system to 246 and am now
    enjoying an extra 8-10 pages of free memory (yeah). NR_OPEN is defined
    in linux/fs.h and limits.h. signal_struct can't be helped, but maybe
    there is a way to attach it to some of the other allocations... Or
    perhaps a kmalloc that better deals with these allocations should be
    written. Any ideas?
