btrfs insane I/O amplification?
....c in emacs) and it took about a minute. Everything went downhill from there. My system was basically idle at the time. (I have very little in the way of diagnostics because I couldn''t do much but hit the reset button after a couple of minutes.)

[RFC PATCH] Btrfs: fix memory leak of orphan block rsv
When adding orphans to an inode''s root, we start a transaction for that root that when ended in several places such as for example extent-tree.c:btrfs_remove_block_group(), inode.c:btrfs_unlink() and inode.c:btrfs_evict_node(), doesn''t result in a commit, that is, inode.c:btrfs_orphan_commit_root() doesn''t get called (via transaction.c:commit_fs_roots()). The respective inode will end up being called by inode.c:btrfs_evict_node...

However, I just noticed that the root partition itself ends up being listed twice with list-filesystems, inspect-os, inspect-get-roots, etc... I'm seeing this in version 1.26, but haven't found anything directly resolving this i...

crash when mounting
Hi guys, I was playing on vmware with btrfs on complete disks /dev/sd{b,c,d,e}. Next I decided to use partitions, so I created /dev/sd{b,c,d,e}1 and used those, worked fine! Afterward, I mistakenly re-ran an old command on the full disk ( mount -t btrfs -o subvol=. /dev/sdb /mnt/ ) notice this is sdb not sdb1,...
