5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx> [ Upstream commit 950db38ff2c01b7aabbd7ab4a50b7992750fa63d ] Now that exec no longer needs to restore the previous value of current->files on error there are no more callers of reset_files_struct so remove it.
