The implementation roughly follows the POSIX specification for rename(). The ordering of operations attempting to minimize the chance for data loss in unexpected circumstances.
The fatrename command is added mostly for the purpose of testing through the sandbox build.
We should not introduce a FAT specific commands. A file-system specific command like 'fatload' does not offer a user benefit over a generic command like 'load'.
Instead, please, create a 'mv' command that will use whatever file-system is on the partition.
Please, add documentation for every new command in doc/usage/cmd/.
The FAT file system is used in SPL where we need to avoid binary size increases.
Please, create a Kconfig symbol for renaming support.
Please, don't add the rename field in fs/fs.c to the driver if the Kconfig symbol is not set or if in SPL.
This should be enough for the linker to eliminate the rename support from the FAT driver if not needed.
