[Cbe-oss-dev] [PATCH 0/4] Updates to sputrace and switch_log behaviour

[Jeremy Kerr]

Hi all,

The following changes are some updates to the way sputrace and the
context switch_log work:

 * Only allow one simultaneous opener
 * Allow read() to return before filling the entire buffer

Comments are welcome.

Cheers,


Jeremy

      powerpc/spufs: sputrace: only enable logging on open(), prevent multiple openers
      powerpc/spufs: sputrace: don't block until the read buffer is full
      powerpc/spufs: use state_mutex for switch_log locking, and prevent multiple openers
      powerpc/spufs: don't require full buffer in switch_log read
