Stefan Berger bfd6b8270a swtpm: cuse: Lock thread_busy_lock reading thread_busy (Coverity) 
Coverity is complaining that thread_busy needs to be locked before
reading. For consistency reasons now also lock thread_busy before reading
it. However, in this case it does not make a difference whether this lock
is held when reading thread_busy since file_ops_lock is held when the
thread_busy flag is set and when it is read with a call to this function
(worker_thread_is_busy). Also while the thread is busy no further commands
can be submitted and it can then reset the thread_busy flag without holding
the file_ops_lock.

SWTPM - Software TPM Emulator
      David Safford safford@us.ibm.com
      Stefan Berger stefanb@us.ibm.com

The SWTPM package provides TPM emulators with different front-end interfaces
to libtpms. TPM emulators provide socket interfaces (TCP/IP and Unix) and
the Linux CUSE interface for the creation of multiple native /dev/vtpm* devices.

The SWTPM package also provides several tools for using the TPM emulator,
creating certificates for a TPM, and simulating the manufacturing of
a TPM by creating a TPM's EK and platform certificates etc. Please read 
the READMEs in the individual tool's directory under src/.

Please consult the Wiki for information about swtpm:
