03afe9ba70 nandfs_meta_bread() calls bread() which can set bp to NULL in some
error cases. Calling brelse() with a NULL pointer is not allowed,
so only call brelse() when the bp is non-NULL.

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...

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.
