    xfs: add a shrinker to background inode reclaim · 9bf729c0
    Dave Chinner 提交于
    On low memory boxes or those with highmem, kernel can OOM before the
    background reclaims inodes via xfssyncd. Add a shrinker to run inode
    reclaim so that it inode reclaim is expedited when memory is low.
    
    This is more complex than it needs to be because the VM folk don't
    want a context added to the shrinker infrastructure. Hence we need
    to add a global list of XFS mount structures so the shrinker can
    traverse them.
