Wrong page freed on preallocate_pmds() failure exit
Note that pmds[i] is simply uninitialized at that point... Granted, it's very hard to hit (you need split page locks *and* kmalloc(sizeof(spinlock_t), GFP_KERNEL) failing), but the code is obviously bogus. Introduced by commit 09ef4939850a ("x86: add missed pgtable_pmd_page_ctor/dtor calls for preallocated pmds") Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Cc: Kirill A.
