Ard Biesheuvel 00cacd0f4b efivarfs: revert "fix memory leak in efivarfs_create()" ... BugLink: https://bugs.launchpad.net/bugs/1908562 [ Upstream commit ff04f3b6f2 ] The memory leak addressed by commit fe5186cf12 is a false positive: all allocations are recorded in a linked list, and freed when the filesystem is unmounted. This leads to double frees, and as reported by David, leads to crashes if SLUB is configured to self destruct when double frees occur. So drop the redundant kfree() again, and instead, mark the offending pointer variable so the allocation is ignored by kmemleak.
