At least two flashes exists that have the concept of a minimum write unit, similar to NAND pages, but no other NAND characteristics. Therefore, rename the minimum write unit to "writesize" for all flashes, including NAND. Signed-off-by: NJoern Engel <joern@wh.fh-wedel.de>

Let's avoid the potential for forgetting to set ref->next_in_ino, by doing it within jffs2_link_node_ref() instead. This highlights the ugliness of what we're currently doing with xattr_datum and xattr_ref structures -- we should find a nicer way of dealing with that.

If __totlen is going away, we need to pass the length in separately. Also stop callers from needlessly setting ref->next_phys to NULL, since that's done for them... and since that'll also be going away soon. Signed-off-by: NDavid Woodhouse <dwmw2@infradead.org>

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.

I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

This patch replaces the current CONFIG_JFFS2_FS_NAND, CONFIG_JFFS2_FS_NOR_ECC and CONFIG_JFFS2_FS_DATAFLASH with a single configuration option - CONFIG_JFFS2_FS_WRITEBUFFER. The only functional change of this patch is that the slower div/mod calculations for SECTOR_ADDR(), PAGE_DIV() and PAGE_MOD() are now always used when CONFIG_JFFS2_FS_WRITEBUFFER is enabled.

For Dataflash, can_mark_obsolete = false and the NAND write buffering code (wbuf.c) is used. Since the DataFlash chip will automatically erase pages when writing, the cleanmarkers are not needed - so cleanmarker_oob = false and cleanmarker_size = 0 DataFlash page-sizes are not a power of two (they're multiples of 528 bytes). The SECTOR_ADDR macro (added in the previous core patch) is replaced with a (slower) div/mod version if CONFIG_JFFS2_FS_DATAFLASH is selected.

DataFlash page-sizes are not a power of two (they're multiples of 528 bytes). There are a few places in JFFS2 code where sector_size is used as a bitmask. A new macro (SECTOR_ADDR) was defined to calculate these sector addresses. For non-DataFlash devices, the original (faster) bitmask operation is still used. In scan.c, the EMPTY_SCAN_SIZE was a constant of 1024. Since this could be larger than the sector size of the DataFlash, this is now basically set to MIN(sector_size, 1024). Addition of a jffs2_is_writebuffered() macro. Signed-off-by: NAndrew Victor <andrew@sanpeople.com> Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
