What do you mean by "a writeback time of 24 hours"? Do you mean
creating a new field in the inode which specifies when the writeback
should happen? I still worry about the dirty inode list getting
somewhat long large in the strictatime && lazytime case, and the inode
bloat nazi's coming after us for adding a new field to struct inode
structure.
Or do you mean trying to abuse the dirtied_when field in some way?
