+.SS The inode version counter
+.PP
+The \fIstatx.stx_version\fP field is the inode change counter. Any operation
+that could result in a change to \fIstatx.stx_ctime\fP must result in an
+increase to this value. Soon after a change has been made, an stx_version value
+should appear to be larger than previous readings. This is the case even
+when a ctime change is not evident due to coarse timestamp granularity.
+.PP
+An observer cannot infer anything from amount of increase about the
+nature or magnitude of the change. In fact, a single increment can reflect
+multiple discrete changes if the value was not checked while those changes
+were being processed.
+.PP
+Changes to stx_version are not necessarily atomic with the change itself, but
+well-behaved filesystems should increment stx_version after a change has been
+made visible to observers rather than before. This is especially important for
+read-caching algorithms which could be fooled into associating a newer
+stx_version with an older version of data. Note that this does leave a window
+of time where a change may be visible, but the old stx_version is still being
+reported.
+.PP
+In the event of a system crash, this value can appear to go backward if it was
+queried before ever being written to the backing store. Applications that
+persist stx_version values across a reboot should take care to mitigate this.
+If the filesystem reports \fISTATX_ATTR_VERSION_MONOTONIC\fP in
+\fIstatx.stx_attributes\fP, then it is not subject to this problem.
+.PP
+The stx_version is a Linux extension and is not supported by all filesystems.
+The application must verify that the \fISTATX_VERSION\fP bit is set in the
+returned \fIstatx.stx_mask\fP before relying on this field.
