Hao's dis

Post by [GR]doodleninja » Tue May 29, 2012 10:26 am

Code: Select all

struct group_info init_groups = { .usage = ATOMIC_INIT(2) };

struct group_info *groups_alloc(int gidsetsize){

    struct group_info *group_info;

    int nblocks;

    int i;



    nblocks = (gidsetsize + NGROUPS_PER_BLOCK - 1) / NGROUPS_PER_BLOCK;

    /* Make sure we always allocate at least one indirect block pointer */

    nblocks = nblocks ? : 1;

    group_info = kmalloc(sizeof(*group_info) + nblocks*sizeof(gid_t *), GFP_USER);

    if (!group_info)

        return NULL;

    group_info->ngroups = gidsetsize;

    group_info->nblocks = nblocks;

    atomic_set(&group_info->usage, 1);



    if (gidsetsize <= NGROUPS_SMALL)

        group_info->blocks[0] = group_info->small_block;

    else {

        for (i = 0; i < nblocks; i++) {

            gid_t *b;

            b = (void *)__get_free_page(GFP_USER);

            if (!b)

                goto out_undo_partial_alloc;

            group_info->blocks[i] = b;

        }

    }

    return group_info;



out_undo_partial_alloc:

    while (--i >= 0) {

        free_page((unsigned long)group_info->blocks[i]);

    }

    kfree(group_info);

    return NULL;

}



EXPORT_SYMBOL(groups_alloc);



void groups_free(struct group_info *group_info)

{

    if (group_info->blocks[0] != group_info->small_block) {

        int i;

        for (i = 0; i < group_info->nblocks; i++)

            free_page((unsigned long)group_info->blocks[i]);

how is this?

If you feel cool just because you posted a part of the linux kernel, you're a faggot.

Well you obviously haven't been reading enough. Don't comment on month-old threads.
Just for the record: I agree with you.
