Subject: [PATCH] rseq: Delete duplicate if statement in rseq_virt_userspace_exit()
Date: Tue, 18 Nov 2025 13:52:13 +0300 [thread overview]
Message-ID: <aRxP3YcwscrP1BU_@stanley.mountain> (raw)
This if statement is indented weirdly. It's a duplicate and doesn't
affect runtime (beyond wasting a little time). Delete it.
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>

This was introduced in commit 32034df66b5f ("rseq: Switch to TIF_RSEQ if
supported") but it doesn't cause a bug, so there is no Fixes tag.
