Jeff Mahoney 47f365eb57 hfs: fix oops on mount with corrupted btree extent records ... A particular fsfuzzer run caused an hfs file system to crash on mount. This is due to a corrupted MDB extent record causing a miscalculation of HFS_I(inode)->first_blocks for the extent tree. If the extent records are zereod out, it won't trigger the first_blocks special case. Instead it falls through to the extent code which we're still in the middle of initializing. This patch catches the 0 size extent records, reports the corruption, and fails the mount.
