* Btrfs: Make ACLs return EOPNOTSUPP for nowJosef Bacik2008-09-25
| | | | | | | | | | | | | | There was a slight problem with ACL's returning EINVAL when you tried to set an ACL. This isn't correct, we should be returning EOPNOTSUPP, so I did a very ugly thing and just commented everybody out and made them return EOPNOTSUPP. This is only temporary, I'm going back to implement ACL's, but Chris wants to push out a release so this will suffice for now. Also Yan suggested setting reada to -1 in the delete case to enable backwards readahead, and in the listxattr case I moved path->reada = 2; to after the if (!path) check so we can avoid a possible null dereference. Thank you, Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Btrfs: Add full_scan parameter to find_search_startYan2008-09-25
| | | | | | | | | | | | This patch adds a new parameter 'full_scan' to 'find_search_start', thereby 'find_search_start' can know whether 'find_free_extent' is in full scan phrase. I feel that 'find_search_start' should skip calling 'btrfs_find_block_group' when 'find_free_extent' is in full scan phrase. In my test on a 2GB volume, Oops occurs when space usage is about 76%. After apply the patch, Oops occurs when space usage is near 100%. Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: Add block group pinned accounting backYan2008-09-25
| | | | | | | | | This patch adds a helper function 'update_pinned_extents' to extent-tree.c. The usage of the helper function is similar to 'update_block_group', the last parameter of the function indicates pin vs unpin. Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Properly delete csum item in btrfs_truncate_in_trans.Yan2008-09-25
| | | | | | | | | | 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: Chris 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: Chris Mason <chris.mason@oracle.com>
* Btrfs: Fix u32 overflow in dirty_and_release_pages.Yan2008-09-25
| | | | | | | | | | | 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: Chris Mason <chris.mason@oracle.com>

* Btrfs: Fix a number of inline extent problems that Yan Zheng reported.Chris Mason2008-09-25
| | | | | | | | | | | | | | | | | | 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>

* Minor fix for btrfs_csum_file_block.Yan2008-09-25
| | | | | | | | | | 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: Chris Mason <chris.mason@oracle.com>
* Fix inline extent handling in btrfs_get_extentYan2008-09-25
| | | | | | | | | | | | 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: Chris Mason <chris.mason@oracle.com>

* Fix ENOTEMPTY check in btrfs_rmdirYan2008-09-25
| | | | | | | | | | | 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.

| | | | | | | | | 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.
