When 'item_end' is equal to 'inode->i_size', 'found_type' is updated and current item is skipped. This behavior is correct for extent item, but incorrect for csum item. For example, there is a csum item with 'offset == 0'. When deleting the inode, 'inode->i_size' is set to 0, so the csum item isn't deleted. Signed-off-by: NChris Mason <chris.mason@oracle.com>

Don't set hint_byte to EXTENT_MAP_INLINE when 'end == extent_end' or 'start == key.offset' . The inline extent will be truncated in these cases. Signed-off-by: NChris Mason <chris.mason@oracle.com>

When calculating the size of inline extent, inode->i_size should also be take into consideration, otherwise sys_write may drop some data silently. You can test this bug by: #dd if=/dev/zero bs=4k count=1 of=test_file #dd if=/dev/zero bs=2k count=1 of=test_file conv=notrunc Signed-off-by: NChris Mason <chris.mason@oracle.com>

There is a 'finish_wait', but no 'prepare_to_wait' . So I think that the 'prepare_to_wait' is missing. The second change is according to the name of variable. Signed-off-by: NChris Mason <chris.mason@oracle.com>

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: NChris 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: NChris Mason <chris.mason@oracle.com>

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: NChris Mason <chris.mason@oracle.com>

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: NChris Mason <chris.mason@oracle.com>

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: NChris Mason <chris.mason@oracle.com>

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: NChris Mason <chris.mason@oracle.com>

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: NChris Mason <chris.mason@oracle.com>
