Hou Tao e319cdc895 bpf: Disable migration when destroying inode storage ... When destroying inode storage, it invokes bpf_local_storage_destroy() to remove all storage elements saved in the inode storage. The destroy procedure will call bpf_selem_free() to free the element, and bpf_selem_free() calls bpf_obj_free_fields() to free the special fields in map value (e.g., kptr). Since kptrs may be allocated from bpf memory allocator, migrate_{disable|enable} pairs are necessary for the freeing of these kptrs. To simplify reasoning about when migrate_disable() is needed for the freeing of these dynamically-allocated kptrs, let the caller to guarantee migration is disabled before invoking bpf_obj_free_fields(). Therefore, the patch adds migrate_{disable|enable} pair in bpf_inode_storage_free(). The migrate_{disable|enable} pairs in the underlying implementation of bpf_obj_free_fields() will be removed by the following patch.
