2008-02-08udf: fix adding entry to a directoryJan Kara
When adding directory entry to a directory, we have to properly increase length of the last extent. Handle this similarly as extending regular files - make extents always have size multiple of block size (it will be truncated down to proper size in udf_clear_inode()).

2008-02-08udf: cleanup directory offset handlingJan Kara
Position in directory returned by readdir is offset of directory entry divided by four (don't ask me why). Make this conversion only when reading f_pos from userspace / writing it there and internally work in bytes. It makes things more easily readable and also fixes a bug (we forgot to divide length of the entry by 4 when advancing f_pos in udf_add_entry()).

2007-07-31UDF: fix UID and GID mount option ignoranceCyrill Gorcunov
This patch fix weird behaviour of UDF mounting procedure. To get UID changed (for now) we have to type mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point and specifying two uid at once is strange a bit. So with the patch we are able to mount without additional 'uid=ignore' option. The same for GID option is done. This patch will not break current mount scheme (with two option).

2007-06-16udf: fix possible leakage of blocksJan Kara
We have to take care that when we call udf_discard_prealloc() from udf_clear_inode() we have to write inode ourselves afterwards (otherwise, some changes might be lost leading to leakage of blocks, use of free blocks or improperly aligned extents). Also udf_discard_prealloc() does two different things - it removes preallocated blocks and truncates the last extent to exactly match i_size. We move the latter functionality to udf_truncate_tail_extent(), call udf_discard_prealloc() when last reference to a file is dropped and call udf_truncate_tail_extent() when inode is being removed from inode cache (udf_clear_inode() call). We cannot call udf_truncate_tail_extent() earlier as subsequent open+write would find the last block of the file mapped and happily write to the end of it, although the last extent says it's shorter.

Make UDF work correctly for files larger than 1GB. As no extent can be longer than (1<<30)-blocksize bytes, we have to create several extents if a big hole is being created.

2006-09-27[PATCH] inode-diet: Eliminate i_blksize from the inode structureTheodore Ts'o
This eliminates the i_blksize field from struct inode. Filesystems that want to provide a per-inode st_blksize can do so by providing their own getattr routine instead of using the generic_fillattr() function. Note that some filesystems were providing pretty much random (and incorrect) values for i_blksize.

2006-03-25[PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget optionsPhillip Susi
As Pekka Enberg pointed out, with the if still following the else, you can still get a null uid written to the disk if you specify a default uid= without uid=forget. In other words, if the desktop user is uid=1000 and the mount option uid=1000 is given ( which is done on ubuntu automatically and probably other distributions that use hal ), then if any other user besides uid 1000 owns a file then a 0 will be written to the media as the owning uid instead.

2006-03-08[PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget optionsPhillip Susi
Fix a bug in udf where it would write uid/gid = 0 to the disk for files owned by the id given with the uid=/gid= mount options. It also adds 4 new mount options: uid/gid=forget and uid/gid=ignore. Without any options the id in core and on disk always match. Giving uid/gid=nnn specifies a default ID to be used in core when the on disk ID is -1. uid/gid=ignore forces the in core ID to allways be used no matter what the on disk ID is. uid/gid=forget forces the on disk ID to always be written out as -1. The use of these options allows you to override ownerships on a disk or disable ownwership information from being written, allowing the media to be used portably between different computers and possibly different users without permissions issues that would require root to correct.

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!
