Input/output error when target is a folder in a bcachefs filesystem

[SorrelArticulata]

Bug appeared in last few months, prior to this sshfs and bcachefs had no issues.

When trying to do anything in an sshfs mount:

$ ls remote 
ls: cannot access 'remote': Input/output error

sftp to the same remote folders works perfectly. Target system's kernel is 6.15.6_1 and bcachefs-tools is 1.25.2

Running sshfs with debugging:

$ sshfs destination: remote -o  debug
