> With that tool, they find that most filesystems drop a lot of error codes:

I recently switched my work notebook to XFS, so looking at this table makes me kinda happy, even if I had bad experiences with XFS in the past (a forced turnoff thanks to a crash in X11 was sufficient to put my system in a unbootable state, trying to recover it with xfs_repair broke it completely; also I suffered with 0-size files randomly appearing after forced reboots quite constantly).

I know for a long time that XFS is probably one of the most well written filesystems for Linux, even if the user case seems to be more focused in servers with uninterrupted power supply than desktops and notebooks.
