Name | Describe |
---|---|
minimum_image_size | minimum_image_size - Estimate the minimum acceptable size of an image |
is_dump_unreclaim_slabs | Print out unreclaimble slabs info when unreclaimable slabs amount is greater* than all user memory (LRU pages) |
global_dirtyable_memory | global_dirtyable_memory - number of globally dirtyable pages* Return: the global number of pages potentially available for dirty* page cache. This is the base value for the global dirty limits. |
balance_dirty_pages | alance_dirty_pages() must be called by processes which are generating dirty* data |
wb_over_bg_thresh | wb_over_bg_thresh - does @wb need to be written back?*@wb: bdi_writeback of interest* Determines whether background writeback should keep writing @wb or it's* clean enough.* Return: %true if writeback should continue. |
