Subject[PATCH] orangefs: inode: Optimized variable usage in orangefs_* correlation functions
Date
These functions are optimized as follows.
1. Remove some variables to initialize the assignment, they are assigned
first.
2. Removes the cast part of a variable assignment of type void*.
3. The orangefs_inode variable is directly assigned at the definition.
