NAME

       error::inode-uprobes - limitations of inode-uprobes

DESCRIPTION

       The uprobes kernel facility introduced in Linux 3.5 aims to supplant the earlier out-of-tree utrace patch
       to enable user-space probing.  There have been some functional limitations in inode-uprobes that preclude
       some systemtap constructs.  Over time, we hope these regressions will be corrected.

       function.return probes
              process.function().return  probes  require "return-probes" or "uretprobes" functionality, that has
              not been implemented yet in the kernel.  Until it is re-added, consider using  process.statement()
              probes placed on source line numbers at the function's return statements.

       function.statement.absolute probes
              In  utrace-equipped  kernels, systemtap made it possible to address probes by literal addresses in
              the process virtual memory address space.  The new inode-uprobes does not have this capability.
