167 When this tunable is set, all chunks larger than this value in bytes are

173 If this tunable is not set, the default value is set to @samp{131072} bytes and
183 The value of this tunable is the minimum size (in bytes) of the top-most,
187 If this tunable is not set, the default value is set as 128 KB and the
197 The value of this tunable is maximum number of chunks to allocate with
198 @code{mmap}.  Setting this to zero disables all use of @code{mmap}.
200 The default value of this tunable is @samp{65536}.
211 The default value of this tunable is 2 for 32-bit systems and 8 for 64-bit
222 The default value of this tunable is @code{0}, meaning that the limit on the
248 per-thread cache, the arenas are used to meet the request.  At this

437 stack cache exceeds this size, unused thread stacks are returned to
438 the kernel, to bring the cache size below this limit.
589 If the hardware supports memory tagging, this tunable can be used to
590 control the way @theglibc{} uses this feature.  At present this is only
611 support in the kernel if this tunable has any non-zero value.
