[LU-12885] improve variable naming to clarify code usage

• Type: Improvement
• Resolution: Unresolved
• Priority: Minor
• Assignee: Andreas Dilger
• Reporter: Andreas Dilger

Description

There are lots of places in the code that have very generic variable names like "flags" or "mask" that are confusing to distinguish in places, because it isn't clear what the type of values those flags hold.

Add named enums for the variables where possible to make it very clear what type of flag is being used, and/or rename the variable to help make this clear. In a couple of cases the variable type is determined by the kernel API and cannot be changed.
