[PATCH 10/24] unpack-trees: don't shadow global var the_index

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This function mark_new_skip_worktree() has an argument named the_index
which is also the name of a global variable. While they have different
types (the global the_index is not a pointer) mistakes can easily
happen and it's also confusing for readers. Rename the function
argument to something other than the_index.
