Possible Improvements

• Can the implementation of the algorithm for kallsyms be further improved after Lorenzo’s patches

• Why the lsm inode cache uses so much more objects than the ext4 cache? Does the increased size reflect in increased performance? Why the ext4 object size is so huge?

$ sudo cat /proc/slabinfo | grep inode
ext4_inode_cache  147068 148596   1168   28    8 : tunables    0    0    0 : slabdata   5307   5307      0
