From a4d7f34d0210344d2e25e5af1c2e61057422521d Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Sun, 11 Nov 2007 21:17:57 +0100 Subject: Revert "inotail.c: Decrement n_units before calling tail_pipe_from_begin" This reverts commit 21cddfba5f53ed0ad9d8f14bc1555c57cad9790e. Makes inotail -n +0 work again.
