Subject: [PATCH hurd 3/5] ext2fs: tune the size of the inode cache
The node cache uses a fixed number of buckets giving it a linear
access complexity, although with a small constant factor. Paper over
this issue by increasing the number of buckets.
* ext2fs/inode.c (INOHSZ): Increase from 512 to 8192 entries.
