* reiserfs: use open_bdev_exclChristoph Hellwig2008-04-30
| | | | | | | | | | | | | | | Use the proper helper to open a blockdevice by name for filesystem use, this makes sure it's properly claimed (also added for open-by-number) and gets rid of the struct file abuse. Tested by mounting a reiserfs filesystem with external journal.

* reiserfs: remove first_zero_hintJeff Mahoney2007-10-19
| | | | | | | | | | | | | | The first_zero_hint metadata caching was never actually used, and it's of dubious optimization quality. This patch removes it. It doesn't actually shrink the size of the reiserfs_bitmap_info struct, since that doesn't work with block sizes larger than 8K. There was a big fixme in there, and with all the work lately in allowing block size > page size, I might as well kill the fixme as well.

* [PATCH] reiserfs: on-demand bitmap loadingJeff Mahoney2006-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | This is the patch the three previous ones have been leading up to. It changes the behavior of ReiserFS from loading and caching all the bitmaps as special, to treating the bitmaps like any other bit of metadata and just letting the system-wide caches figure out what to hang on to. Buffer heads are allocated on the fly, so there is no need to retain pointers to all of them. The caching of the metadata occurs when the data is read and updated, and is considered invalid and uncached until then. I needed to remove the vs-4040 check for performing a duplicate operation on a particular bit. The reason is that while the other sites for working with bitmaps are allowed to schedule, is_reusable() is called from do_balance(), which will panic if a schedule occurs in certain places. The benefit of on-demand bitmaps clearly outweighs a sanity check that depends on a compile-time option that is discouraged.

* [PATCH] reiserfs: fix is_reusable bitmap check to not traverse the bitmap ↵Jeff Mahoney2006-10-01
| | | | | | | | | | | | | | | | | | | | info array There is a check in is_reusable to determine if a particular block is a bitmap block. It verifies this by going through the array of bitmap block buffer heads and comparing the block number to each one. Bitmap blocks are at defined locations on the disk in both old and current formats. Simply checking against the known good values is enough. This is a trivial optimization for a non-production codepath, but this is the first in a series of patches that will ultimately remove the buffer heads from that array.

* reiserfs: run scripts/Lindent on reiserfs codeLinus Torvalds2005-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was a pure indentation change, using: scripts/Lindent fs/reiserfs/*.c include/linux/reiserfs_*.h to make reiserfs match the regular Linux indentation style. As Jeff Mahoney <jeffm@suse.com> writes: The ReiserFS code is a mix of a number of different coding styles, sometimes different even from line-to-line. Since the code has been relatively stable for quite some time and there are few outstanding patches to be applied, it is time to reformat the code to conform to the Linux style standard outlined in Documentation/CodingStyle. This patch contains the result of running scripts/Lindent against fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the code can be made to look better, but I'd rather keep those patches separate so that there isn't a subtle by-hand hand accident in the middle of a huge patch. To be clear: This patch is reformatting *only*. A number of patches may follow that continue to make the code more consistent with the Linux coding style. Hans wasn't particularly enthusiastic about these patches, but said he wouldn't really oppose them either. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
