# Validate that without no-holes we do not get a i_size that is after a gap in
|
|
# the file extents on disk when punching a hole past i_size. This is fixed by
|
|
# the following patches
|
|
#
|
|
# btrfs: use the file extent tree infrastructure
|
|
# btrfs: replace all uses of btrfs_ordered_update_i_size
