     143 *  Updated bdbuf file system cache by [wiki:ChrisJohns ChrisJohns]. The new code does not disable pre-emption in the cache code or in the standard drivers in RTEMS such as the ATA driver. The updated code added configuration parameters to confdefs.h to change the number of read ahead buffers and the number of write buffers. The swap out task has a configurable sample period and modified buffers to be written have a configurable hold time before being committed to disk. The code has been tested on a mvf5235 with the RAM, FLASH and NV disks and on the PC with the ATA, RAM and NV disks.
