Warner Losh	cfe87f0076	Naughty NANDFS was using hidden unused flag, hiding the fact that the ... flag was used and wasn't really available. Change the name without fixing any laying issues that might be present in NANDFS' use of this flag.	2014-07-07 23:21:07 +00:00
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.

Grzegorz Bernacki	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.
