Hi! I try to install the yaffs2 to the lastest kernel, but the kernel compliation failed! I fix it and test in kernel 3.14.6. The patch fixes the following issues in file:1. the typedef of kuid_t and kgid_t is removed from the kernel 3.14. 2. file_operations.readdir is removed from the kernel 3.11; use file_operations.iterator instead. 3. create_proc_entry, proc_dir_entry.write_proc and proc_dir_entry.read_proc is removed from the kernel 3.10; use proc_create and file_operations instead. 4. MTD_BOLCK_MAJOR is moved from linux/mtd/mtd.h to include/uapi/linux/major.h after the kernel 3.13.
