[PATCH 0/4] Linux lseek and {f}truncate syscall consolidation

[Adhemerval Zanella]

Hi all,

This is my ongoing Linux syscall consolidation to avoid code duplication
and to try make new ports easier.  The patchset contains update version
of my previous patches for lseek [1], truncate [2], and ftruncate [3].

[3] https://sourceware.org/ml/libc-alpha/2016-08/msg00812.html

Adhemerval Zanella (4):
  Add INTERNAL_SYSCALL_CALL
  Consolidate lseek/lseek64/llseek implementations
  Consolidate Linux ftruncate implementations
  Consolidate Linux truncate implementations
