Summary
fs: fix UAF/GPF bug in nilfs_mdt_destroy
Details

In the Linux kernel, the following vulnerability has been resolved:

fs: fix UAF/GPF bug in nilfsmdtdestroy

In allocinode, inodeinitalways() could return -ENOMEM if securityinodealloc() fails, which causes inode->iprivate uninitialized. Then nilfsismetadatafileinode() returns true and nilfsfreeinode() wrongly calls nilfsmdtdestroy(), which frees the uninitialized inode->i_private and leads to crashes(e.g., UAF/GPF).

Fix this by moving securityinodealloc just prior to thiscpuinc(nr_inodes)
