2008-09-25Btrfs: Fix typo and memory leak in extent-tree.cYan1-6/+8
This patch fixes a typo in update_block_group and memory leak in btrfs_free_block_groups. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Fix a number of inline extent problems that Yan Zheng reported.Chris Mason8-38/+135
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>

2008-09-25Minor fix for btrfs_csum_file_block.Yan1-6/+4
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>
2008-09-25Fix inline extent handling in btrfs_get_extentYan1-16/+18
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>

2008-09-25Fix ENOTEMPTY check in btrfs_rmdirYan1-1/+4
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: Chris Mason <chris.mason@oracle.com>
2008-09-25btrfs_inode_by_name return random value.Yan1-2/+3
When inode is found, the return value is from the uninitialized variable 'ret'. -- Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Tune the automatic defrag codeChris Mason2-44/+26
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: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Fix for insert_inline_extent to handle offset != 0Yan1-9/+12
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>
2008-09-25Btrfs: Fix split_leaf to detect when it is extending an itemChris Mason1-51/+27
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: Chris Mason <chris.mason@oracle.com>

2008-09-25Btrfs: Optimize csum insertion to create larger items when possibleChris Mason3-2/+38
This reduces the number of calls to btrfs_extend_item and greatly lowers the cpu usage while writing large files. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2008-09-25Btrfs: sysfs compile fixupJens Axboe1-3/+2
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: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: KM_IRQ0 usage in end_io handlingJens Axboe1-0/+4
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: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: Fix bi_end_io() functions on > 2.6.23 kernelsJens Axboe1-0/+25
It now returns void and it is never called for partial completions, so the bio->bi_size check must go. Signed-off-by: Chris Mason <chris.mason@oracle.com>
