Subject: [PATCH] dm: multipath: fix rr_add_path order
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5d55fdf94998db1df9ee7f1def8806bfd0e5ff73;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] dm: multipath: fix rr_add_path order

When adding paths to the round-robin path selector, their order gets inverted,
which is not desirable.

Fix by replacing list_add() with list_add_tail().
