btrfs: add the ability to use NO_FLUSH for data reservations

2022-09-29T15:08:28+00:00

In order to accommodate NOWAIT IOCB's we need to be able to do NO_FLUSH
data reservations, so plumb this through the delalloc reservation
system.

btrfs: make btrfs_delalloc_reserve_space take btrfs_inode

2020-07-27T10:55:36+00:00

All of its children take btrfs_inode so bubble up this requirement to
btrfs_delalloc_reserve_space's interface and stop calling BTRFS_I
internally.

Instead of calling BTRFS_I on the passed vfs_inode take btrfs_inode
directly.

No point in taking an inode only to get btrfs_fs_info from it, instead
take btrfs_fs_info directly.

btrfs: remove the start argument from btrfs_free_reserved_data_space_noquota()

2020-07-27T10:55:21+00:00

The start argument for btrfs_free_reserved_data_space_noquota() is only
used to make sure the amount of bytes we decrement from the bytes_may_use
counter of the data space_info object is aligned to the filesystem's
sector size. It serves no other purpose.

All its current callers always pass a length argument that is already
aligned to the sector size, so we can make the start argument go away.
In fact its presence makes it impossible to use it in a context where we
just want to free a number of bytes for a range for which either we do
not know its start offset or for freeing multiple ranges at once (which
are not contiguous).

This change is preparatory work for a patch (third patch in this series)
that makes relocation of data block groups that are not full reserve less
data space.

btrfs: migrate the delalloc space stuff to it's own home

2019-07-04T15:26:17+00:00

We have code for data and metadata reservations for delalloc.  There's
quite a bit of code here, and it's used in a lot of places so I've
separated it out to it's own file.  inode.c and file.c are already
pretty large, and this code is complicated enough to live in its own
space.
