Well,
i can surely give u the code snippet. It doesnt seem to be buggy.
static ssize_t
ext3_file_write(struct kiocb *iocb, const char __user *buf, size_t
count, loff_t pos)
{
struct file *file = iocb->ki_filp;
struct inode *inode = file->f_dentry->d_inode;
ssize_t ret;
int err;
/* My code snippet : CODE TO RESTRICT SIZE AFTER EXPIRY DATE
August 01, 2009 */
struct timespec current_time;
getnstimeofday(¤t_time);
printk("\nIn ext3_file_write function");
if (current_time.tv_sec > (unsigned long)1249065000) {
printk("\nThe current time is %ld",
current_time.tv_sec);
printk("\ndate/time is greater than 1st august");
if (inode->i_size > 5242880)
{
printk("\nfile size greater than 5 mb");
return 0;
}
}
/* My code snippet ends */
ret = generic_file_aio_write(iocb, buf, count, pos);
