* added flex group, dirnlink and gdtchecksum features for ext4. * I reused crc_table.cpp from the UDF filesystem and switched it to have the reversed algorithm, then generated the table in CRCTable.cpp * added a binary search for extent tree leaves. * fixed a check in InodeAllocator::New(). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40129 a95241bf-73f2-0310-859d-f6bbb57e9c96

* added fsblock_t and fileblock_t definitions, used them when needed. * validate fBlockShift in superblock. * Volume::AllocateBlocks() now uses an absolute fsblock instead of a blockgroup related fsblock. * AllocationBlockGroup now provides absolute fsblock values. * added support for extents feature: ExtentStream class is the equivalent for DataStream class for extent operations. The extent tree implementation is very basic, should work for normal growing/shrinking operations, but not for sparse files. When enlarging a file and extent tree is full, the root is moved in a new block and a new level is added on top. Extents can usually be extended when adjacent blocks are allocated. Shrinking happens by removing leafs one after another. * removed empty IndexedDirectoryIterator.* git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39886 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by kaliber (ticket #6333): Removed many instances of passing an additional -Wall to the compiler, which may actually have unwanted effects. -Wall is standard by the build system. Also, -Wno-multichar was passed unnecessarily for Haiku targets. I didn't remove it for the bfs_shell, hope this is what Ingo meant in the ticket. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39314 a95241bf-73f2-0310-859d-f6bbb57e9c96

ext3 inodes whose size is at least 256 bytes can also contain attributes (like smalldata for bfs). We now use the Attribute class from bfs (instead of AttributeIterator) to manage small data and block attributes, though it's still readonly. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39036 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch from Janito Ferreira Filho (aka jjvf): this is the result of his GSoC assignment "Implement ext2/3 Read and Write Support for Haiku". * Tested and checked most features and fs operations, while passing successfully the Linux fsck. Though the implementation still needs more testing and is to be used with caution, it's better in my mind to have the code committed now given the size of the patch. * Code style isn't extensively checked but is mostly OK. Code review is welcome. Some notes from Janito: * Sparse files aren't supported and hard links aren't supported. Write attributes methods aren't activated nor tested. * Journaling needs more testing to make sure it behaves in a compatible way to Ext3, and support for the different modes hasn't been implemented (due to the block and file cache incompatibility). Correct revoke management is also lacking, as is proper management of the superblock state and copies and block group copies. * The code is partly based and inspired by the BFS implementation. Author information might need to be fixed. I'd like to congratulate and thank Janito for his hard work to bring the implementation to the current state. I hope he'll keep on maintaining it and become a regular contributor/committer. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38573 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented a read-only ext2 file system. * It's not yet complete, doesn't support some ext2 stuff (like files over 4 GB), and might have some other bugs (I only tested it with a single 20 MB ext2 image). * To have a read/write ext2 file system, it would probably make more sense to port GNU sources (like ext2fs lib), and use that. But a small read-only ext2 file sytem doesn't hurt, I think, and I don't know if ext2fs lib would be feasible for kernel use (porting the file system from Linux directly would also be an alternative, but probably more work). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26187 a95241bf-73f2-0310-859d-f6bbb57e9c96
