- Fix the "bytes" output of the per_cpu stat file
The tracefs/per_cpu/cpu*/stats "bytes" was giving bogus values as the
accounting was not accurate. It is suppose to show how many used bytes are
still in the ring buffer, but even when the ring buffer was empty it would
still show there were bytes used.
- Fix a bug in eventfs where reading a dynamic event directory (open) and then
creating a dynamic event that goes into that diretory screws up the accounting.
On close, the newly created event dentry will get a "dput" without ever having
a "dget" done for it. The fix is to allocate an array on dir open to save what
dentries were actually "dget" on, and what ones to "dput" on close.
