4Subject: [PATCH 02/11] misc/create_inode.c: copy files recursively
5
6Use opendir() and readdir() to read the native directory, then use
7lstat() to identify the file type and call the corresponding function to
8add the file to the filesystem, call the populate_fs() recursively if it
9is a directory.
10
11NOTE: the libext2fs can't create the socket file.

13Upstream-Status: Backport
