From 4757d7dff65b56f2115038ad1615725f31806787 Mon Sep 17 00:00:00 2001 From: Anton Altaparmakov Date: Sat, 25 Jun 2005 17:24:08 +0100 Subject: NTFS: Change ntfs_map_runlist_nolock() to only decompress the mapping pairs if the requested vcn is inside it. Otherwise we get into problems when we try to map an out of bounds vcn because we then try to map the already mapped runlist fragment which causes ntfs_mapping_pairs_decompress() to fail and return error. Update ntfs_attr_find_vcn_nolock() accordingly.
