Btrfs: Implement basic support for -ENOSPC · 1832a6d5

由 Chris Mason 提交于 12月 21, 2007

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

Btrfs: Add mount option to turn off data cow · be20aa9d

由 Chris Mason 提交于 12月 17, 2007

A number of workloads do not require copy on write data or checksumming.
mount -o nodatasum to disable checksums and -o nodatacow to disable
both copy on write and checksumming.

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

Properly delete csum item in btrfs_truncate_in_trans. · 008630c1

由 Yan 提交于 11月 07, 2007

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.

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

Fix inline extent handling in btrfs_get_extent · 689f9346

由 Yan 提交于 10月 29, 2007

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)

Fix ENOTEMPTY check in btrfs_rmdir · 134d4512

由 Yan 提交于 10月 25, 2007

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.
