semaphore. Note some filesystems (i.e. remote ones) provide no
protection for i_size so you will need to use the BKL.
->open() locking is in-transit: big lock partially moved into the methods.
The only exception is ->open() in the instances of file_operations that never
end up in ->i_fop/->proc_fops, i.e. ones that belong to character devices
(chrdev_open() takes lock before replacing ->f_op and calling the secondary
method. As soon as we fix the handling of module reference counters all
instances of ->open() will be called without the BKL.
Note: ext2_release() was *the* source of contention on fs-intensive
loads and dropping BKL on ->release() helps to get rid of that (we still
grab BKL for cases when we close a file that had been opened r/w, but that
