[Bug libc/24744] New: Remove copy_file_range emulation


https://sourceware.org/bugzilla/show_bug.cgi?id=24744

            Bug ID: 24744
           Summary: Remove copy_file_range emulation
           Product: glibc
           Version: 2.30
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

The kernel is evolving this interface rapidly, and our emulation is no longer
faithful: Among other things, we do not detect overlapping copies (which is
quite hard outside the kernel).  The kernel also plans to support cross-device
copies.
