* Fix EXTENT_MAP_INLINE off by one in btrfs_drop_extentsYan2008-09-25
| | | | | | | | 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>

* Btrfs: Fix for insert_inline_extent to handle offset != 0Yan2008-09-25
| | | | | | | | | 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: Chris Mason <chris.mason@oracle.com>

* Btrfs: Use balance_dirty_pages_nr on btree blocksChris Mason2008-09-25
| | | | | | | | btrfs_btree_balance_dirty is changed to pass the number of pages dirtied for more accurate dirty throttling. This lets the VM make better decisions about when to force some writeback. Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Btrfs: Add more synchronization before creating a snapshotChris Mason2007-09-10
| | | | | | | | File data checksums are only done during writepage, so we have to make sure all pages are written when the snapshot is taken. This also adds some locking so that new writes don't race in and add new dirty pages. Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Btrfs: Add run time btree defrag, and an ioctl to force btree defragChris Mason2007-08-07
| | | | | | | | | | | This adds two types of btree defrag, a run time form that tries to defrag recently allocated blocks in the btree when they are still in ram, and an ioctl that forces defrag of all btree blocks. File data blocks are not defragged yet, but this can make a huge difference in sequential btree reads. Signed-off-by: Chris Mason <chris.mason@oracle.com>
