-Subject: [PATCH] efivarfs: revert "fix memory leak in efivarfs_create()"
-
-The memory leak addressed by commit fe5186cf12e3 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.
-
-Cc: Vamshi K Sthambamkadi <vamshi.k.sthambamkadi@gmail.com>
-Fixes: fe5186cf12e3 ("efivarfs: fix memory leak in efivarfs_create()")
-Reported-by: David Laight <David.Laight@aculab.com>
