btrfs: compress: put variables defined per compress type in struct to make cache friendly
Below variables are defined per compress type.
- struct list_head comp_idle_workspace[BTRFS_COMPRESS_TYPES]
- spinlock_t comp_workspace_lock[BTRFS_COMPRESS_TYPES]
- int comp_num_workspace[BTRFS_COMPRESS_TYPES]
- atomic_t comp_alloc_workspace[BTRFS_COMPRESS_TYPES]
- wait_queue_head_t comp_workspace_wait[BTRFS_COMPRESS_TYPES]
BTW, while accessing one compress type of these variables, the next or
before address is other compress types of it.
So this patch puts these variables in a struct to make cache friendly.
