Subject: [PATCH] userfaultfd: Fix vma iterator conversion.
Date: Tue, 10 Jan 2023 18:43:03 +0000 [thread overview]
Message-ID: <20230110184247.1268710-1-Liam.Howlett@oracle.com> (raw)
An extra vma_iter_set() was added to one of the loops over the VMAs.
Remove this set as it is suboptimal and unnecessary.
