btrfs-progs: handle invalid num_stripes in sys_array

We can handle the special case of num_stripes == 0 directly inside
btrfs_read_sys_array. The BUG_ON in btrfs_chunk_item_size is there to
catch other unhandled cases where we fail to validate external data,
like in btrfs-show-super.

8 years agobtrfs-progs: mkfs: allow --data DUP for single device
Zhao Lei [Thu, 19 Nov 2015 09:36:24 +0000 (17:36 +0800)]
btrfs-progs: mkfs: allow --data DUP for single device

Current code don't support DUP profile on single device, except it
is in mixed mode, because of following reasons:

1: Some SSD do deduplication internally, so the duplication on
   the filesystem side has no effect.
2: On a physical device, if the entire disk broken, --data DUP does not
   help.
3: Half performance compared to single profile.
4: We have a workaround: create multi-partition on a single device,
   and btffs will treat them as multi device.

Instead of refusing --data DUP, we give the user a choice and print
a wrning.

Test:
1: Tested by xfstests
   Run with modified xfstests, I add test items of -d dup in single
   device into btrfs/* and common/rc, run tests of btrfs/*,
   with all mount option, no regression diffed with v4.3.
2: Tested by btrfs-progs
   Checked following commands in "-m dup -d dup" fs with memleck

btrfs-progs: Rename variables in btrfs_add_to_fsid

There are two total_bytes in btrfs_add_to_fsid(), local variable
of total_bytes means fs_total_bytes, and device->total_bytes means
device's total_bytes.
And device's total_bytes in argument is named block_count in current
code.

This patch rename:
 total_bytes -> fs_total_bytes
 block_count -> device_total_bytes

btrfs-progs: fix uninitialized copy of btrfs_fs_devices list

Noticed that at print_one_uuid() some of the members of btrfs_fs_devices
contained some junk values. It took a while to dig this further, and found
that we make a local copy of the btrfs_fs_devices list at
search_umounted_fs_uuids() and wasn't initialized properly.

Fixed using using calloc instead of malloc.
