Subject: ext4: add missing kfree() on error return path in add_new_gdb()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c49bafa3842751b8955a962859f42d307673d75d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ext4: add missing kfree() on error return path in add_new_gdb()

We added some more error handling in b40971426a "ext4: add error
checking to calls to ext4_handle_dirty_metadata()".  But we need to
call kfree() as well to avoid a memory leak.
