Subject: io_uring/fdinfo: show SQEs for no array setup
X-Git-Tag: v6.19-rc1~169^2~46
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0ecf0e6748120842700efc5dbf22a18580f7efcf;p=thirdparty%2Fkernel%2Flinux.git

io_uring/fdinfo: show SQEs for no array setup

The sq_head indicates the index directly in the submission queue when
the IORING_SETUP_NO_SQARRAY option is used, so use that instead of
skipping showing the entries.
