Description

In the Linux kernel, the following vulnerability has been resolved:\nnfs: pass explicit offset/count to trace events\nnfs_folio_length is unsafe to use without having the folio locked and a\ncheck for a NULL ->f_mapping that protects against truncations and can\nlead to kernel crashes. E.g. when running xfstests generic/065 with\nall nfs trace points enabled.\nFollow the model of the XFS trace points and pass in an expl?cit offset\nand length.
