With bigalloc feature enabled we do not support indirect addressing at all so we have to prevent extent addressing to indirect addressing conversion in this case. The problem has been introduced with the commit "ext4: support simple conversion of extent-mapped inodes to use i_blocks" Signed-off-by: Lukas Czerner <lczerner@redhat.com> --- v2: added to the series fs/ext4/migrate.c | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-)
