The fixes do a number of things: 1) Most btrfs_drop_extent callers will try to leave the inline extents in place. It can truncate bytes off the beginning of the inline extent if required. 2) writepage can now update the inline extent, allowing mmap writes to go directly into the inline extent. 3) btrfs_truncate_in_transaction truncates inline extents 4) extent_map.c fixed to not merge inline extent mappings and hole mappings together Signed-off-by:Chris Mason <chris.mason@oracle.com>

Execution should goto label 'insert' when 'btrfs_next_leaf' return a non-zero value, otherwise the parameter 'slot' for 'btrfs_item_key_to_cpu' may be out of bounds. The original codes jump to label 'insert' only when 'btrfs_next_leaf' return a negative value. Signed-off-by: -

1. Reorder kmap and the test for 'page != NULL' 2. Zero-fill rest area of a block when inline extent isn't big enough. 3. Do not insert extent_map into the map tree when page == NULL. (If insert the extent_map into the map tree, subsequent read requests will find it in the map tree directly and the corresponding inline extent data aren't copied into page by the the get_extent function. extent_read_full_page can't handle that case) Signed-off-by: -

The ENOTEMPTY check in btrfs_rmdir isn't reliable. It's possible that the backward search finds . or .. at first, then some other directory entry. In that case, btrfs_rmdir delete . or .. improperly. The patch also fixes a fs_mutex unlock issue in btrfs_rmdir. -- Signed-off-by: -

1) Forced defrag wasn't working properly (btrfsctl -d) because some cache only checks were incorrect. 2) Defrag only the leaves unless in forced defrag mode. 3) Don't use complex logic to figure out if a leaf is needs defrag Signed-off-by: -

This modifies inline extent size calculation, so that insert_inline_extent can handle the case that parameter 'offset' is not zero; it also a few codes to zero uninitialized area in inline extent. Signed-off-by: -

When making room for a new item, it is ok to create an empty leaf, but when making room to extend an item, split_leaf needs to make sure it keeps the item we're extending in the path and make sure we don't end up with an empty leaf. Signed-off-by: -

This reduces the number of calls to btrfs_extend_item and greatly lowers the cpu usage while writing large files. Signed-off-by: -

Just use kobject_set_name(), that works in all kernels (I think...). Kernels newer than 2.6.23 currently fail with: /home/axboe/git/btrfs/btrfs-unstable/sysfs.c:188: error: unknown field 'name' specified in initializer Signed-off-by: -

endio handling is typically called with interrupts disabled, but can also be called with it enabled. So save interrupts before using KM_IRQ0 to be completely safe. Signed-off-by: -

It now returns void and it is never called for partial completions, so the bio->bi_size check must go. Signed-off-by: -

This allows us to defrag huge directories, but skip the expensive defrag case in more common usage, where it does not help as much. Signed-off-by: -
