From: Eric W. Biederman Date: Fri, 20 Nov 2020 23:14:20 +0000 (-0600) Subject: exec: Remove reset_files_struct X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=950db38ff2c01b7aabbd7ab4a50b7992750fa63d;p=linux.git exec: Remove reset_files_struct 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.
