| |
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.
