bc2258da88 Complete MPSAFE VFS interface and remove MNTK_MPSAFE flag. 
Porters should refer to __FreeBSD_version 1000021 for this change as
it may have happened at the same timeframe.

7f725bcd5c Import work done under project/nand (@235533) into head. 
The NAND Flash environment consists of several distinct components:
  - NAND framework (drivers harness for NAND controllers and NAND chips)
  - NAND simulator (NANDsim)
  - NAND file system (NAND FS)
  - Companion tools and utilities
  - Documentation (manual pages)

This work is still experimental. Please use with caution.
