Subject: [PATCH 29/30] lib-fs-resize: Prevent crash resizing FAT with very

 deep directories

Resizing a FAT file system crashes in libparted/fs/r/fat/count.c

flag_traverse_dir() if the length of any path name in the file system

overflows the 512 byte file_name local buffer.  Increase buffer to 4096,

PATH_MAX on Linux.
