Some callers to block-layer commit_write function treat non-zero return as error, notably the loopback mount driver sometimes used in conjunction with JFFS2 on NAND flash for bad block avoidance, etc. Return zero for success as do various other commit_write functions. Signed-off-by:

- assume wbuf may be of size which is not power of 2 - don't make strange assumption about not padding wbuf for DataFlash - use wbuf = DataFlash page and eraseblock >= 8 Dataflash pages From: Peter Menzebach <pm-mtd@mw-itcon.de> Acked-by:

Always keep valid data in reserved_size. It did not cause problems, but the reservation code was unoptimal when centralized summary was active or the size of the erase block was very small. Signed-off-by:

The changes introduced allow to suspend/resume NAND flash. A new state (FL_PM_SUSPENDED) is introduced, as well as routines for mtd->suspend and mtd->resume to put the flash in suspended state from software pov. Signed-off-by:

The goal of summary is to speed up the mount time. Erase block summary (EBS) stores summary information at the end of every (closed) erase block. It is no longer necessary to scan all nodes separetly (and read all pages of them) just read this "small" summary, where every information is stored which is needed at mount time. This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image. Signed-off-by:
