/*
 * Gather statistics for VFS operations:
 *
 * Usage:
 *  - Placing an instance of the VFS_STAT_START macro at the begining
 *    of a function and VFS_STAT_STOP macro at the end of a function
 *    will keep a count of how many times the function is called as well
 *    as the total amount of time spent in the function (elapsed time
 *    between entering and leaving the function).
 *  - Placing an instance of the VFS_INC macro inside a function will
 *    update a call count, but not keep any time statistics.
 *  - Use the command "mmfsadm vfsstats ..." to control and display
 *    vfs statistics:
 *       mmfsadm vfsstats enable    - turn on statistics gathering
 *       mmfsadm vfsstats disable   - turn off statistics gathering
 *       mmfsadm vfsstats reset     - reset all statistics counters
 *       mmfsadm vfsstats show      - display statistics
 *
