btrfs_delalloc_release_space - release data and metadata space for delalloc : inode we're releasing space for : the number of bytes we want to free up

This must be matched with a call to btrfs_delalloc_reserve_space. This is called in the case that we don't need the metadata AND data reservations anymore. So if there is an error or we insert an inline extent.

This function will release the metadata space that was not used and will decrement ->delalloc_bytes and remove it from the fs_info delalloc_inodes list if there are no delalloc bytes left.

btrfs_delalloc_reserve_space - reserve data and metadata space for delalloc : inode we're writing to : the number of bytes we want to allocate

This will do the following things

o reserve space in the data space info for num_bytes o reserve space in the metadata space info based on number of outstanding extents and how much csums will be needed o add to the inodes ->delalloc_bytes o add it to the fs_info's delalloc inodes list.

This will return 0 for success and -ENOSPC if there is no space left.
