From 065cf0958c39600f2062cbeeb5b76929d03c207b Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Mon, 22 Nov 2010 22:50:58 -0800 Subject: [PATCH] * src/names.c: tar: fix bug with --one-file-system --listed-incremental Problem (and idea for fix) reported by Martin Weigel . * src/common.h (is_individual_file): Remove decl. * src/create.c (dump_file0): Replace "is_individual_file (p)" with "top_level". * src/incremen.c (procdir): Replace "!is_individual_file (name_buffer)" with "st->parent". Fix bug with --one-file-system and --listed-incremental. * src/names.c (individual_file_table, register_individual_file): (is_individual_file): Remove.
