[$] Tracing the source of filesystem errors

Date:
Wed, 07 Aug 2024 14:18:21 +0000

Description:
There are lots of places in the kernel where an EINVAL can be
returned to user space, but it is often unclear what the actual underlying
problem is because the errno error codes are too generic.  That is the 
problem that Miklos Szeredi
wanted to discuss in a filesystem session that he led remotely at the 2024 
Linux Storage,
Filesystem, Memory Management, and BPF Summit .  He would like to help
those who are trying to debug problems trace where in the kernel a
particular error code is being generated.
