+@deftp Tunable glibc.pthread.rseq
+The @code{glibc.pthread.rseq} tunable can be set to @samp{0}, to disable
+restartable sequences support in @theglibc{}. This enables applications
+to perform direct restartable sequence registration with the kernel.
+The default is @samp{1}, which means that @theglibc{} performs
+registration on behalf of the application.
+
+Restartable sequences are a Linux-specific extension.
