* [JFFS2] Add erase block summary support (mount time improvement)Ferenc Havasi2005-11-06
| | | | | | | | | | | | | | | | | | 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.

* [JFFS2] Use f->target instead of f->dents for symlink targetArtem B. Bityutskiy2005-11-06
| | | | | | | | | | JFFS2 uses f->dents to store the pointer to the symlink target string (in case the inode is symlink). This is somewhat ugly to use the same field for different reasons. Introduce distinct field f->target for this purpose. Note, f->fragtree, f->dents, f->target may probably be put in a union. Signed-off-by: Artem B.

| * [PATCH] nvidiafb: Geforce 7800 series support addedCalin A. Culianu2005-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Nvidia Geforce 7800 series of cards to the nvidiafb framebuffer driver. All it does is add the PCI device id for the 7800, 7800 GTX, 7800 GO, and 7800 GTX GO cards to the module device table for the nvidiafb.ko driver, so that nvidiafb.ko will actually work on these cards. I also added the relevant PCI device ids to linux/pci_ids.h I tested it on my 7800 GTX here and it works like a charm. I now can get framebuffer support on this card! Woo hoo!! Nothing like 200x75 text mode to make your eyes BLEED. ;) Signed-off-by: Linus Torvalds <torvalds@osdl.org>
