Warner Losh	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.	2014-04-18 17:03:43 +00:00
Warner Losh	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...

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.

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.
