Q&A wrt this patch: - A really short guide to how to get up and running with this filesystem. Reiser4 is a file system based on dancing tree algorithms, and is described at http://www.namesys.com. One should be able to get it up and running just like any of the other filesystems supported by Linux. Configure it to be compiled either builtin or as a module. Create reiser4 filesystem with mkfs.reiser4, mount and use it. More detailed info can be found at http://thebsh.namesys.com/snapshots/LATEST/READ.ME. - The direct URL which people use to obtain the mkfs tool for this filesystem. Also fsck and anything else. Reiser4 userland tools can be obtained at ftp://ftp.namesys.com/pub/reiser4progs. ftp://ftp.namesys.com/pub/reiser4progs/README contains detailed instructions on how to compile and install these tools. Also all reiser4 progs have man pages. - Any known shortcomings, caveats, etc. Reiser4 has been tested on i386 yet only. Quota support is not ready yet. Should be ready soon. Reiser4 was tested extensively, and we got to where the mailing list was not able to hit any bugs, but then we told people that, got an order of magnitude increase in users, and they are able to hit bugs that we are working on now. Reiser's Law of Software Engineering: Each order of magnitude increase in users finds more bugs, in a quantity equal to the previous order of magnitude increase in users. Success for software developers is measured by how long the frustration lasts. Only the very core functionality is working. Exotic plugins, an API for multiple operation transactions and accessing multiple small files in one syscall, compression, inheritance, all have been postponed until after the core functionality is shipped. The compression plugin needs a code review before anyone should use it. - A statement on compatibility with reiserfs3 filesytems. To upgrade from reiserfs V3 to V4, use tar, or sponsor us to write a convertfs. - Bear in mind that people will immediately benchmark this filesytem, and first impressions count. Now is your chance to communicate any tuning guidelines, mount options or whatever which you'd like people to understand BEFORE they start publishing benchmark info. Reiser4 is not tuned for fsync/sync/O_SYNC performance yet. If you see results that are much different from those at www.namesys.com/benchmarks.html, let us know. If you see performance characteristics that don't quite make sense, email reiserfs-list@namesys.com, such things are always of interest. reiser4 is not tuned for mmaping and dirtying more than physical ram like IOzone does. This is quite different in its code path from writing and dirtying more than physical ram. There are those who think that what IOZone does is rarely done by real programs, and therefor we should not bother to optimize what it does. All I know is, this month we are not optimized for it. Please consider its space savings when you benchmark it also.

generic implementaion and changes fs-writeback.c:sync_sb_inodes() to call filesystem's sync_inodes if it is defined or generic implementaion otherwise. This new operation allows filesystem to decide itself what to flush. Reiser4 flushes dirty pages on basic of atoms, not of inodes. sync_sb_inodes used to call address space flushing method (writepages) for every dirty inode. For reiser4 it caused having to commit atoms unnecessarily often. This turned into substantial slowdown. Having this method helped to fix that problem. akpm: this patch needs to be chnaged to remove the `sb' arg. Signed-off-by:

"captured" by some atom. However, outside reiser4 context dirty page can not be captured in some cases, as it is accompanied with specific work (jnode creation, etc). Reiser4 recognizes such "anonymous" pages (i.e. pages that were dirtied outside of reiser4) by the tag PAGECACHE_TAG_DIRTY. Pages dirtied inside reiser4 context are not tagged at all: we don't need this. Indeed, once page is dirtied and captured, it is attached to a jnode (a special header to keep a track of transactions). reiser4_set_page_dirty_internal() was the internal reiser4 function that set dirty bit without tagging the page. Having such internal function led to real problems (incorrect task io accounting, etc. because of not updating this internal "friend"). Solution: The following patch adds a core library function that sets a dirty bit without tagging the page.

bitmap_set: Set specified bit area bitmap_clear: Clear specified bit area bitmap_find_next_zero_area: Find free bit area These are mostly stolen from iommu helper. The differences are: - Use find_next_bit instead of doing test_bit for each bit - Rewrite bitmap_set and bitmap_clear Instead of setting or clearing for each bit. - Check the last bit of the limit iommu-helper doesn't want to find such area - The return value if there is no zero area find_next_zero_area in iommu helper: returns -1 bitmap_find_next_zero_area: return >= bitmap size Signed-off-by:

LZO-compressed kernel images, as well as support for using such images on the x86 and ARM architectures, and support for creating and using LZO-compressed initrd and initramfs images. This patch: The lzo compressor is worse than gzip at compression, but faster at extraction. Here are some figures for an ARM board I'm working on: Uncompressed size: 3.24Mo gzip 1.61Mo 0.72s lzo 1.75Mo 0.48s So for a compression ratio that is still relatively close to gzip, it's much faster to extract, at least in that case. This part contains: - Makefile routine to support lzo compression - Fixes to the existing lzo compressor so that it can be used in compressed kernels - wrapper around the existing lzo1x_decompress, as it only extracts one block at a time, while we need to extract a whole file here - config dialog for kernel compression Signed-off-by:
