2011-03-29yaffs: Add first cut of block summary codeCharles Manning

2010-11-09yaffs: Remove SHORT_NAMES_IN_RAM and WIDE_TNODE_DISABLE configsCharles Manning
These have been removed from Linux as their use is discouraged except for debugging purposes. The logic has also changed for SHORT_NAMES_IN_RAM. This is now negative logic. Set CONFIG_YAFFS_NO_SHORT_NAMES to **disable** short names. Signed-off-by: Charles Manning <cdhmanning@gmail.com>

2010-09-25yaffs Clean up some codeCharles Manning
Clean up some code. eg remove some conditional compilation and obsolete code. Signed-off-by: Charles Manning <cdhmanning@gmail.com>
2010-09-25yaffs Remove obsolete list debugging codeCharles Manning
This code does not work any more so may as well delete it. Signed-off-by: Charles Manning <cdhmanning@gmail.com>

Tighten compilation flags and clean up. More to follow... Signed-off-by: Charles Manning <cdhmanning@gmail.com>
2010-09-09yaffs: Cache object xattrib state.Charles Manning
We cache whether or not an object has xattributes. This is done to get around the problem of the Linux VFS trying to check security capabilities on every write. Assuming that most files don't have security attributes, this code will save on a huge amount of reads and make writing faster. Signed-off-by: Charles Manning <cdhmanning@gmail.com>
2010-09-03yaffs Add stats tracking and control for background gc instrumentationCharles Manning
This allows us to track the impact of background gc. Signed-off-by: Charles Manning <cdhmanning@gmail.com>
2010-08-10yaffs Fix yaffs1 soft delete issueCharles Manning
In some corner cases soft deletion could cause NAND to leak and show up in lost and found. This only impacts yaffs1 mode. Signed-off-by: Charles Manning <cdhmanning@gmail.com>

Signed-off-by: Charles Manning <cdhmanning@gmail.com>
2010-07-21yaffs Refactor yaffs direct device list management, add nand abstraction, ↵Charles Manning
divide up test code This all makes for a far cleaner layout of test code. The new yaffs direct list management allows partitions to be added synamically rather than statically. This is better for OSs that install partitions at runtime (eg. WInCE). The nand abstraction makes it tidier to add a new nand driver to yaffs direct and test code. The test code has been repartitioned to make porting and file management cleaner. Signed-off-by: Charles Manning <cdhmanning@gmail.com>
2010-07-02yaffs Fix scan problem for corrupted tagsCharles Manning
Check that the tags are within reasonable bounds. Without this, subsequent checks can fail causing a mount failure. Signed-off-by: Charles Manning <cdhmanning@gmail.com>

2010-04-16work in progressCharles Manning
2010-03-19Re-enable soft delete for yaffs1 mode.Charles Manning
Soft deletion was disabled because it messed up yaffs2 mode. Soft deletion is not very valuable for yaffs2 mode, but has been re-enabled for yaffs1 mode where it is far more value. Also added a parameter to disable soft delete. Signed-off-by: Charles Manning <cdhmanning@gmail.com>
