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: -
