[PATCH v3 16/49] builtin/apply: move 'update_index' global into 'struct apply_state'

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

 



To libify the apply functionality the 'update_index' variable should
not be static and global to the file. Let's move it into
'struct apply_state'.
