Kent Overstreet	3636ed489a	bcachefs: Deferred btree updates ... Will be used in the future for inode updates, which will be very helpful for multithreaded workloads that have to update the inode with every extent update (appends, or updates that change i_sectors) Also will be used eventually for fully persistent alloc info However - we still need a mechanism for reserving space in the journal prior to getting a journal reservation, so it's not technically safe to make use of this just yet, we could deadlock with the journal full (although not likely to be an issue in practice) Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>	2023-10-22 17:08:12 -04:00
