wb_clear_pending AFAIKS should not be called after the item has been put on the list, except by the worker threads. It could lead to the situation where the refcount is decremented below 0 and cause lots of problems. Presumably the !wb_has_dirty_io case is not a common one, so it can be discovered when the thread wakes up to check? Also add a comment in bdi_work_clear. Signed-off-by:

By the time bdi_work_on_stack gets evaluated again in bdi_work_free, it can already have been deallocated and used for something else in the !on stack case, giving a false positive in this test and causing corruption. Signed-off-by:

If you're going to do an atomic RMW on each list entry, there's not much point in all the RCU complexities of the list walking. This is only going to help the multi-thread case I guess, but it doesn't hurt to do now. Signed-off-by:

We cannot safely ensure that the inodes are all gone at this point in time, and we must not destroy this bdi with inodes having off it. So just splice our entries to the default bdi since that one will always persist. Signed-off-by:

bdi_start_writeback() is currently split into two paths, one for WB_SYNC_NONE and one for WB_SYNC_ALL. Add bdi_sync_writeback() for WB_SYNC_ALL writeback and let bdi_start_writeback() handle only WB_SYNC_NONE. Push down the writeback_control allocation and only accept the parameters that make sense for each function. This cleans up the API considerably. Signed-off-by:

We do this automatically in get_sb_bdev() from the set_bdev_super() callback. Filesystems that have their own private backing_dev_info must assign that in ->fill_super(). Note that ->s_bdi assignment is required for proper writeback! Acked-by:

We need to be able to pass in range_cyclic as well, so instead of growing yet another argument, split the arguments into a struct wb_writeback_args structure that we can use internally. Also makes it easier to just copy all members to an on-stack struct, since we can't access work after clearing the pending bit. Signed-off-by:
