2008-09-25Btrfs: Fix for test_range_bitYan1-0/+5
test_range_bit doesn't properly handle the case: there's a hole at the end of the range and there's no other extent_state after the range. Signed-off-by: Chris Mason <[email protected]>

2008-09-25Btrfs: Implement basic support for -ENOSPCChris Mason1-6/+14
This is intended to prevent accidentally filling the drive. A determined user can still make things oops. It includes some accounting of the current bytes under delayed allocation, but this will change as things get optimized Signed-off-by: Chris Mason <[email protected]>

The attached patch fixes this for me. Not sure if it is correct though.

2008-09-25Btrfs: small fixes for find_lock_delalloc_range.Yan1-1/+3
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: Chris Mason <[email protected]>
2008-09-25Btrfs: Fix a number of inline extent problems that Yan Zheng reported.Chris Mason1-3/+8
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 <[email protected]>

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 <[email protected]>

2007-09-10Btrfs: [PATCH] extent_map: add writepage_end_io hookChristoph Hellwig1-0/+2
XFS updates the ondisk inode size only after the data I/O has finished, so it needs a hook when the writepage end_bio handler has finished. Might not be worth applying as-is as the per-page callback is very ineffcient. What XFS really wants is a callback when writeout of a whole extent has completed. This delayed i_size updates scheme might be worthwile for btrfs aswell, btw. Signed-off-by: Christoph Hellwig <[email protected]> Signed-off-by: Chris Mason <[email protected]>
2007-09-10Btrfs: [PATCH] extent_map: make the writepage_io hook optionalChristoph Hellwig1-1/+6
The writepage_io is not mandatory, e.g. my port of xfs to the extent_map code does not have one for now. So handle a NULL pointer gracefully here. Signed-off-by: Christoph Hellwig <[email protected]> Signed-off-by: Chris Mason <[email protected]>
2007-09-10Btrfs: [PATCH] extent_map: provide generic bmapChristoph Hellwig1-0/+19
generic_bmap is completely trivial, while the extent to bh mapping in btrfs is rather complex. So provide a extent_bmap instead that takes a get_extent callback and can be used by filesystem using the extent_map code.

2007-09-10Btrfs: [PATCH] extent_map: fix locking for bio completionChristoph Hellwig1-6/+8
The bio completion handlers can be run in any context, e.g. when using the old ide driver they run in hardirq context with irqs disabled so lockdep rightfully warns about using write_lock_irq useage in these handlers. This patch switches clear_extent_bit and set_extent_bit to write_lock_irqsave to fix this problem. Signed-off-by: Christoph Hellwig <[email protected]> Signed-off-by: Chris Mason <[email protected]>
