[PATCH v2 29/36] btrfs: pass the fscrypt_info through the replace extent infrastructure

[Josef Bacik]

Prealloc uses the btrfs_replace_file_extents() infrastructure to insert
its new extents.  We need to set the fscrypt context on these extents,
so pass this through the btrfs_replace_extent_info so it can be used in
a later patch when we hook in this infrastructure.
