How about a 64-bit field in struct inode that's used a
Dynamically reduce the size of the nodemask_t in struct inode
The nodemask_t in struct inode can potentially waste a lot of memory if
MAX_NUMNODES is high. For IA64 MAX_NUMNODES is 1024 by default which
results in 128 bytes to be used for the nodemask. This means that the
memory use for inodes may
