[PATCH] hfs, hfsplus: use SLAB_RECLAIM_ACCOUNT and SLAB_MEM_SPREAD flags

[Mikulas Patocka]

Add the flags SLAB_RECLAIM_ACCOUNT and SLAB_MEM_SPREAD to hfs and hfsplus
inode cache, so that it is consistent with other filesystems.

The SLAB_RECLAIM_ACCOUNT flags accounts memory allocated for the inode
cache in the "SReclaimable" field in /proc/meminfo.

The SLAB_MEM_SPREAD spreads the allocated memory across all NUMA nodes,
most other filesystems use this flag.
