The attached patch contains a shared Reed-Solomon Library analogous to the shared zlib. (N)AND FLASH is gaining popularity and there are a lot of ASIC/SoC/FPGA controllers around which implement hardware support for Reed-Solomon error correction. As usual they use different implementations (polynomials etc.). So it's obvious to use a shared library for the common tasks of error correction. A short scan through the kernel revealed that at least the ftape driver uses Reed-Solomon error correction. It could be easily converted to use the shared library code. The encoder/decoder code is lifted from the GPL'd userspace RS-library written by Phil Karn. I modified/wrapped it to provide the different functions which we need in the MTD/NAND code. The library is tested in extenso under various MTD/NAND configurations. The lib should be usable for other purposes right out of the box. Adjustment for currently not implemented functionality is an easy task. I'm willing to take the maintainership of the library. Signed-Off-By:

The orphan list holds inodes that need to be truncated on recovery. In the O_DIRECT case, it's used if we extend the inode --- the truncate on recovery means we'll recover the newly-allocated disk blocks if we crash after the IO starts but before i_size is updated on disk. Now, the orphan list is *also* used to delete inodes that are unlinked but still-open. Those get truncated but also deleted on recovery. The orphan list is held both in memory and on disk. So the rules are that the inode can't be reclaimed while on the orphan list. There are only two cases --- either the inode is actively being written(O_DIRECT) or truncated (in which case the inode is by definition not going to be reused), or it's unlinked but still open (again, non-reclaimable). But in the case where you're truncating or write(O_DIRECT)ing a file that is *ALSO* unlinked, there's a problem --- the final unlink would put the inode on the orphan list, but the write/truncate would try to add/remove it. End result is that the inode disappears from the orphan list while it's still unlinked-but-in-use. That's just a leak-on-crash, it's not going to be detectable in normal use. But it's still a bug, and the way we fix it is for direct-IO and truncate not to do the ext3_orphan_del if the file is unlinked (ie. i_nlink==0). Signed-off-by:

The following patches provide an interface to the lease subsystem in the current VFS locking code. NFSv4 delegations and Samba op-locks share most architecture features. The version 4 NFS server delegation implementation should use leases to co-ordinate behavior between local, Samba, and NFS access. The main design points are - Seperate the fcntl interface from the file_lock FL_LEASE processing in fcntl_setlease, creating __setlease() called by fcntl_setlease() - Add new lock_manager callbacks to enable lease properties to be set, leases to be broken, and leases to be cleaned up: with default callbacks preserving the current fcntl_setlease properties. - Add a new interface, setlease() which also calls __setlease(), and remove_lease() for kernel lease managers (e.g. the v4 NFS server) This patch: Add a lock manager copy lock callback to locks_copy_lock() so that nfsd can set lease properties.

This patch adds a REISERFS_UNSUPPORTED_OPT flag to denote when a mount option is allowable, but is unsupported in the running configuration. This allows the potential for the set of mount options to be consistent, regardless of what features the kernel is compiled with. Rather than failing the mount, a warning is issued and the mount succeeds. Signed-off-by:

This patch adds efficeon as a cpu option, and makes a small update to the transmeta cpuid code. (i wasn't sure if the various doc files are UTF-8... if they are, then the e should be a U-275 ;) The compile options may not be ideal, but they're probably close. i used -march=pentium3, but -march=pentium4 would have been good enough too. The cpuid update teaches transmeta.c about the extended processor revision present in cpuid level 0x80860002... the external documentation does not indicate how to break apart this field, and instructs only that the 32-bit value should be printed in hex (alas).

I've noticed that under specific circumstances the "console=" kernel parameter is ignored. This happens when EARLY_PRINTK is enabled and the serial console is the only available. In this case unregister_console() when called for the early console sets preferred_console back to -1 replacing the value that was recorded by console_setup() -- the order of calls is as follows: 1. register_console() -- for the early console, 2. console_setup() -- recording the console index for the real console, 3. unregister_console() -- for the early console, erasing the console index recorded above, 4. register_console() -- for the real console, picking up the first device available, instead of the selected one. I've observed this problem with a DECstation system using ttyS3 -- its default console device from the firmware's point of view. The solution is to restore the setting of "console=" upon unregister_console(). This made a snapshot of 2.4.26 work for me. I wasn't able to test the changes with 2.6 because DECstation drivers don't support it yet, but the code responsible for console selection appears functionally the same. So I've concluded it needs the same change. Here's a patch. Signed-off-by:

At the moment, the NLM cookie length is fixed to 8 bytes, while 1024 is the theoretical maximum. FreeBSD uses 16 bytes, Mac OS X uses 20 bytes. Therefore we need to make the length dynamic (which I set to 32 bytes). This patch is based on an old patch for Linux 2.4.23-pre9, which I changed to patch properly (also added some stylish NIPQUAD fixes). From: Neil Brown <neilb@cse.unsw.edu.au> Further lockd tidyups. - NIPQUAD everywhere that is appropriate - use XDR_QUADLEN in more places as appropriate - discard QUADLEN which is a lockd-specific version of XDR_QUADLEN Signed-off-by:

Attached is a patch that fixes the fragmentation that Badri noticed with kmem_cache_alloc_node. kmem_cache_alloc_node tries to allocate memory from a given node. The current implementation contains two bugs: - the node aware code was used even for !CONFIG_NUMA systems. Fix: inline function that redefines kmem_cache_alloc_node as kmem_cache_alloc for !CONFIG_NUMA. - the code always allocated a new slab for each new allocation. This caused severe fragmentation. Fix: walk the slabp lists and search for a matching page instead of allocating a new page. - the patch also adds a new statistics field for node-local allocs. They should be rare - the codepath is quite slow, especially compared to the normal kmem_cache_alloc. Signed-Off-By:

There is a useless AND in swp_type() function. We just shifted right SWP_TYPE_SHIFT() bits the value from the swp_entry_t, and then we AND it with "(1 << 5) - 1" (which is a mask corresponding to the number of bits used by "type"). Signed-off-by:

I don't know what this is trying to do. It might be some kind of artifact from when get_pgd_slow() was removed. The expanded expression with __pa() ends up looking something like this: (unsigned long)(u64)(u32)pmd-PAGE_OFFSET and that is just nutty because pmd is a pointer now, anyway.
