doesn't advertise an erase block size.

1bbf66051b Take out the hack to write -1's to non-NAND. Always do a BIO_DELETE on 
the ranges we want to erase. This is nicer to SSDs that want TRIMs
anyway.

875ac64f3e More properly account for free/reserved segments to avoid deadlock or 
worse when filling up a device and then trying to erase files to make
space. Without enough space, you can't do that. Also, ensure that the
metadata writes don't generate ENOSPC. They will be retried later
since the buffers are still dirty...

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.
