From: Breno Leitao Date: Mon, 16 Oct 2023 13:47:43 +0000 (-0700) Subject: io_uring/cmd: Pass compat mode in issue_flags X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5fea44a6e05b86bf49019fbbf2ab30098d03e0dc;p=linux.git io_uring/cmd: Pass compat mode in issue_flags Create a new flag to track if the operation is running compat mode. This basically check the context->compat and pass it to the issue_flags, so, it could be queried later in the callbacks.
