    inode: Make unused inode LRU per superblock · 98b745c6
    Dave Chinner 提交于
    The inode unused list is currently a global LRU. This does not match
    the other global filesystem cache - the dentry cache - which uses
    per-superblock LRU lists. Hence we have related filesystem object
    types using different LRU reclaimation schemes.
    
    To enable a per-superblock filesystem cache shrinker, both of these
    caches need to have per-sb unused object LRU lists. Hence this patch
    converts the global inode LRU to per-sb LRUs.
    
    The patch only does rudimentary per-sb propotioning in the shrinker
    infrastructure, as this gets removed when the per-sb shrinker
    callouts are introduced later on.
