pipcet opened a new issue, #16237:
URL: https://github.com/apache/nuttx/issues/16237
### Description / Steps to reproduce the issue
The procfs code behaves strangely when dealing with a path which is a prefix
of a valid procfs entry: changing directory to such a prefix works rather than
failing, and the apparent entries correspond to the remaining path, with one
byte omitted.
In this configuration, `/proc/net` exists, but `/proc/n` doesn't:
```
nsh> cd /proc/n
nsh> ls
/proc/n:
t
t/
nsh>
```
I would have expected behavior analogous to:
```
nsh> cd /proc/x
nsh: cd: chdir failed: 2
nsh>
```
