Steps to reproduce:

1. Create template
2. Create LLD with key vfs.fs.discovery
3. In Filter section, create filters
   1. Type of calculation: AND

1. 1. #FSTYPE does not match '^tmpfs.*'
   2. #FSTYPE does not match '^devfs|^proc|^tmpfs'

Result:

It is possible to filter on macro FSNAME, but not on FSTYPE
Expected:
Screenshot of relevant LLD part:

Result: creation of numerous triggers: 

 

Partial returned data from LLD:
