Revision 606c812eb1d5b5fb0dd9e330ca94b52d7c227830 authored by Liam R. Howlett on 18 June 2023, 00:47:08 UTC, committed by Linus Torvalds on 18 June 2023, 16:32:17 UTC
The error unrolling was leaving the VMAs detached in many cases and
leaving the locked_vm statistic altered, and skipping the unrolling
entirely in the case of the vma tree write failing.
Fix the error path by re-attaching the detached VMAs and adding the
necessary goto for the failed vma tree write, and fix the locked_vm
statistic by only updating after the vma tree write succeeds.
Fixes: 763ecb035029 ("mm: remove the vma linked list")
