From f559180176a8650a78edb5be73935f51cd6a0064 Mon Sep 17 00:00:00 2001 From: Yevgeny Popovych Date: Tue, 5 Jun 2018 13:11:01 +0300 Subject: [PATCH] fs: btrfs: Fix not all CHUNK_ITEMs being read from CHUNK_TREE This causes errors when translating logical addresses to physical: btrfs_map_logical_to_physical: Cannot map logical address to physical btrfs_file_read: Error reading extent The behavior of btrfs_map_logical_to_physical() is to stop traversing CHUNK_TREE when it encounters first non-CHUNK_ITEM, which makes only some portion of CHUNK_ITEMs being read. Change it to skip over non-chunk items.
