pipes is implemented with multiple clients using signals.
when somewhere it is found that while modifying a file (which intern form a version later on) that the last two modifications were wrong then certainly we need to switch to the one which was correct ok, now the question is ???
in the RCS the data of the previous wrong versions also exist, which shouldn’t? why is it so? what is the way to delete it?
e.g., 1.1
1.2
1.3
1.2 and 1.3 were found wrong
switched to 1.1 and modified it
as 1.1.1.1
1.1.1.2 and so on ….
but when we checkin into RCS the information abt modifications took place as 1.2 and 1.3 also exist…

In character driver ,we initialize the semaphore variable through sema_init(struct semaphore *sem,int val).so my question is how can we check semaphore variable value in our code and where this value get stored in struct semaphore…..
as we check the value through :
printk(KERN_INFO “semophore count= %d\n”,(int)&sculldev->sem.count);
but it shows the negative value….
Is there any other way to check the semophore variable…Please guide…
