#     vfs: Fix EOVERFLOW testing in put_compat_statfs64
#     
#     Today, put_compat_statfs64() disallows nearly any field value over
#     2^32 if f_bsize is only 32 bits, but that makes no sense.
#     compat_statfs64 is there for the explicit purpose of providing 64-bit
#     fields for f_files, f_ffree, etc.  And f_bsize is always only 32 bits.
#     
#     As a result, 32-bit userspace gets -EOVERFLOW for i.e.  large file
#     counts even with -D_FILE_OFFSET_BITS=64 set.
#     
#     In reality, only f_bsize and f_frsize can legitimately overflow
#     (fields like f_type and f_namelen should never be large), so test
#     only those fields.
#     
#     This bug was discussed at length some time ago, and this is the proposal
#     Al suggested at https://lkml.org/lkml/2018/8/6/640.  It seemed to get
#     dropped amid the discussion of other related changes, but this
#     part seems obviously correct on its own, so I've picked it up and
#     sent it, for expediency.
