From 1ee889fdf409ce68c1e3b62912333a5cc69acaa0 Mon Sep 17 00:00:00 2001 From: Mateusz Guzik Date: Wed, 1 Oct 2025 01:29:57 +0200 Subject: [PATCH] f2fs: don't call iput() from f2fs_drop_inode() iput() calls the problematic routine, which does a ->i_count inc/dec cycle. Undoing it with iput() recurses into the problem. Note f2fs should not be playing games with the refcount to begin with, but that will be handled later. Right now solve the immediate regression.
