# Verify that check can detect compressed extent without csum as an error
|
|
#
|
|
# There is report about nodatasum inode which has compressed extent, and when
|
|
# its compressed data is corrupted, decompress screws up the whole kernel.
|
|
#
|
|
# While btrfs(5) shows that nodatasum will disable data CoW and compression,
|
|
# there was bug in kernel that allowed this combination. And in above case,
|
|
# lzo problem can lead to more serious kernel memory corruption since btrfs
|
|
# completely depends its csum to prevent corruption.
|
|
#
|
|
# So btrfs check should report such compressed extent without csum as error.
