mm: don't use __vma_adjust() in __split_vma()
Use the abstracted locking and maple tree operations. Since __split_vma() is the only user of the __vma_adjust() function to use the insert argument, drop that argument. Remove the NULL passed through from fs/exec's shift_arg_pages() and mremap() at the same time. Link: https://lkml.kernel.org/r/20230120162650.984577-44-Liam.Howlett@oracle.com Signed-off-by: Liam R.
