|
|
*
|
|
* arena_ind: Arena from which this extent came, or all 1 bits if
|
|
* unassociated.
|
|
*
|
|
* slab: The slab flag indicates whether the extent is used for a slab
|
|
* of small regions. This helps differentiate small size classes,
|
|
* and it indicates whether interior pointers can be looked up via
|
|
* iealloc().
|
|
*
|
|
* committed: The committed flag indicates whether physical memory is
|
|
* committed to the extent, whether explicitly or implicitly
|
|
* as on a system that overcommits and satisfies physical
|
|
* memory needs on demand via soft page faults.
|
|
*
|
|
* dumpable: The dumpable flag indicates whether or not we've set the
|
|
* memory in question to be dumpable. Note that this
|
|
* interacts somewhat subtly with user-specified extent hooks,
|
|
* since we don't know if *they* are fiddling with
|
|
* dumpability (in which case, we don't want to undo whatever
|
|
* they're doing). To deal with this scenario, we:
|
|
* - Make dumpable false only for memory allocated with the
|
|
* default hooks.
|
|
* - Only allow memory to go from non-dumpable to dumpable,
|
|
* and only once.
|
|
* - Never make the OS call to allow dumping when the
|
|
* dumpable bit is already set.
|
|
* These three constraints mean that we will never
|
|
* accidentally dump user memory that the user meant to set
|
|
* nondumpable with their extent hooks.
|
|
*
|
|
*
|
|
* zeroed: The zeroed flag is used by extent recycling code to track
|
|
* whether memory is zero-filled.
|
|
*
|
|
* state: The state flag is an extent_state_t.
|
|
*
|
|
* szind: The szind flag indicates usable size class index for
|
|
* allocations residing in this extent, regardless of whether the
|
|
* extent is a slab. Extent size and usable size often differ
|
|
* even for non-slabs, either due to sz_large_pad or promotion of
|
|
* sampled small regions.
|
|
*
|
|
* nfree: Number of free regions in slab.
|
|
*
|
|
* bin_shard: the shard of the bin from which this extent came.
|
|
*
|
|
* sn: Serial number (potentially non-unique).
|
|
*
|
|
* Serial numbers may wrap around if !opt_retain, but as long as
|
|
* comparison functions fall back on address comparison for equal
|
|
* serial numbers, stable (if imperfect) ordering is maintained.
|
|
*
|
|
* Serial numbers may not be unique even in the absence of
|
|
* wrap-around, e.g. when splitting an extent and assigning the same
|
|
* serial number to both resulting adjacent extents.
