btrfs: add btrfs_reserve_data_bytes and use it

2020-10-07T10:06:52Z

Create a new function btrfs_reserve_data_bytes() in order to handle data reservations. This uses the new flush types and flush states to handle making data reservations. This patch specifically does not change any functionality, and is purposefully not cleaned up in order to make bisection easier for the future patches. The new helper is identical to the old helper in how it handles data reservations. We first try to force a chunk allocation, and then we run through the flush states all at once and in the same order that they were done with the old helper. Subsequent patches will clean this up and change the behavior of the flushing, and it is important to keep those changes separate so we can easily bisect down to the patch that caused the regression, rather than the patch that made us start using the new infrastructure.

btrfs: use the btrfs_space_info_free_bytes_may_use helper for delalloc

2020-10-07T10:06:52Z

We are going to use the ticket infrastructure for data, so use the btrfs_space_info_free_bytes_may_use() helper in btrfs_free_reserved_data_space_noquota() so we get the btrfs_try_granting_tickets call when we free our reservation.

btrfs: make btrfs_delalloc_reserve_space take btrfs_inode

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. Signed-off-by: Nikolay Borisov Reviewed-by: David Sterba Signed-off-by: David Sterba
