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.
