Btrfs: Split the extent_map code into two parts · d1310b2e

由 Chris Mason 提交于 1月 24, 2008

There is now extent_map for mapping offsets in the file to disk and
extent_io for state tracking, IO submission and extent_bufers.

The new extent_map code shifts from [start,end] pairs to [start,len], and
pushes the locking out into the caller.  This allows a few performance
optimizations and is easier to use.

A number of extent_map usage bugs were fixed, mostly with failing
to remove extent_map entries when changing the file.

Btrfs: Fix hole insertion corner cases · 5f56406a

由 Chris Mason 提交于 1月 22, 2008

There were a few places that could cause duplicate extent insertion,
this adjusts the code that creates holes to avoid it.

lookup_extent_map is changed to correctly return all of the extents in a
range, even when there are none matching at the start of the range.

A number of workloads do not require copy on write data or checksumming.

In nodatacow mode, copy on write is still performed when a given extent

Btrfs: Fix a number of inline extent problems that Yan Zheng reported. · 179e29e4

由 Chris Mason 提交于 11月 01, 2007

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
