    SubjectDoubt (bug?) in dup_mmap()
    Hi all,

    In the function dup_mmap() in kernel/fork.c,

    file = tmp->vm_file;
    if (file) {
    struct inode *inode = file->f_dentry->d_inode;
    get_file(file);
    if(tmp->vm_flags & VM_DENYWRITE)
    atomic_dec(&inode->i_writecount);

    After this piece of code, shouldn't there be :

    else
    atomic_inc(&inode->i_writecount);

    as this is a read-write mapping ?


    Bye,
    Abhi.
