The patch titled
fdtable: Delete pointless code in dup_fd()
has been removed from the -mm tree. Its filename is
fdtable-delete-pointless-code-in-dup_fd.patch
This patch was dropped because an updated version will be merged
------------------------------------------------------
Subject: fdtable: Delete pointless code in dup_fd()
From: Vadim Lobanov <vlobanov@xxxxxxxxxxxxx>
The dup_fd() function creates a new files_struct and fdtable embedded inside
that files_struct, and then possibly expands the fdtable using expand_files().
The out_release error path is invoked when expand_files() returns an error
code. However, when this attempt to expand fails, the fdtable is left in its
original embedded form, so it is pointless to try to free the associated
fdarray and fdsets.
