Analyze and fix the following issue in the Linux kernel code: netfs: Fix missing zero-length check in unbuffered write
Problem Details: Fix netfs_unbuffered_write_iter() to return immediately if generic_write_checks() returns 0, indicating there's nothing to write. Note that netfs_file_write_iter() already does this. Also, whilst we're at it, put in checks for the size being zero before we even take the locks. Note that generic_write...
