* Embed a struct path into struct nameidata instead of nd->{dentry,mnt}Jan Blunck2008-02-141-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

* [MTD] [NAND] cs553x_nand: command line partitioning supportMart Raudsepp2008-02-091-3/+28
| | | | | | | | | | | | | | Implements kernel command line partitioning support for the CS5535/CS5536 chipsets driver. For that the following is done: * cs553x_cleanup(): try the cleanup for all chip selects to not leak memory * Assign a unique name for each chip select to be separately addressable in the command line mtd-id portion(s) * Use the already defined PIN_OPT_IDE constant where appropriate for readability * Include command line partitioning support when CONFIG_MTD_PARTS is set Signed-off-by: Mart Raudsepp <mart.raudsepp@artecdesign.ee> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| * [MTD] Add mtd panic_write function pointerRichard Purdie2008-02-071-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MTDs are well suited for logging critical data and the mtdoops driver allows kernel panics/oops to be written to flash in a blackbox flight recorder fashion allowing better debugging and analysis of crashes. Any kernel oops in user context can be easily handled since the kernel continues as normal and any queued mtd writes are scheduled. Any kernel oops in interrupt context results in a panic and the delayed writes will not be scheduled however. The existing mtd->write function cannot be called in interrupt context so these messages can never be written to flash. This patch adds a panic_write function pointer that drivers can optionally implement which can be called in interrupt context. It is only intended to be called when its known the kernel is about to panic and we need to write to succeed. Since the kernel is not going to be running for much longer, this function can break locks and delay to ensure the write succeeds (but not sleep).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the physmap mapping driver to support multiple resources for non-identical NOR chips that will be concatenated together when selected. This is needed for example for Intel 48F4400 512MBit chips, since they consist of 2 single different NOR chips with different geometries. The first (lower) one has botton boot sectors and the 2nd (upper) has top boot sectors. This currently isn't handled correctly by calling the physmap driver once with only one resource covering both chips in one memory region. The same geometrie is used for both chips. With this patch the following resource structure can be used to describe the 48F4400 chip correctly: static struct resource board_nor_resource[] = { [0] = { .start = 0xf8000000, .end = 0xfbffffff, .flags = IORESOURCE_MEM, }, [1] = { .start = 0xfc000000, .end = 0xffffffff, .flags = IORESOURCE_MEM, } }; Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

For example, for 256MiB Samsung OneNAND flash there might be from 0 to 40 bad initial eraseblocks, which is about 2%. When UBI is used as the base system, one needs to know the exact amount of good physical eraseblocks, because this number is needed to create the UBI image which is put to the devices during production. But this number is not know, which forces us to use the minimum number of good physical eraseblocks. And UBI additionally reserves some percentage of physical eraseblocks for bad block handling (default is 1%), so we have 1-3% of PEBs reserved at the end, depending on the amount of initial bad PEBs. But it is desired to always have 1% (or more, depending on the configuration). Solution: this patch adds an "auto-resize" flag to the volume table. The volume which has the "auto-resize" flag will automatically be re-sized (enlarged) on the first UBI initialization. UBI clears the flag when the volume is re-sized. Only one volume may have the "auto-resize" flag. So, the production UBI image may have one volume with "auto-resize" flag set, and its size is automatically adjusted on the first boot of the device.
