- Properly set B_NOTMETA on media buffers, which allows swapcache to distinguish between data and meta-data buffers.
This ensures that a user desiring to only swapcache meta-data does not blow all the SSD swap on file data, particularly if there is an excessive amount of file data.
- Greatly improves bulkfree performance on hard drives when SSD swapcache is enabled for meta-data only.
