Summary
shmem: use ramfs_kill_sb() for kill_sb method of ramfs-based tmpfs
Details

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

shmem: use ramfskillsb() for kill_sb method of ramfs-based tmpfs

As the ramfs-based tmpfs uses ramfsinitfscontext() for the initfscontext method, which allocates fc->sfsinfo, use ramfskill_sb() to free it and avoid a memory leak.
