If anyone has any objections, please let me know. ------------------ From: Namjae Jeon [ Upstream commit f7c0366e0a80bf8cd5eacc5479927abb50958b5e ] The copychunk error mapping handles -EACCES in an independent if statement. The following error chain therefore reaches its final else clause and overwrites STATUS_ACCESS_DENIED with STATUS_UNEXPECTED_IO_ERROR. Join the -EACCES check to the remaining error chain so an access failure is returned as STATUS_ACCESS_DENIED.
