Subject: [IPV4]: Fix garbage collection of multipath route entries
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=85259878499d6c428cba191bb4e415a250dcd75a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[IPV4]: Fix garbage collection of multipath route entries

When garbage collecting route cache entries of multipath routes
in rt_garbage_collect(), entries were deleted from the hash bucket
'i' while holding a spin lock on bucket 'k' resulting in a system
hang.  Delete entries, if any, from bucket 'k' instead.
