- B_TRIM_DEVICE on a ram disk frees all requested pages. Reading from a trimmed page returns all 0s. This can be used with fstrim to release memory for the parts not used by the filesystem, without unregistering then registering the device. - Add icon and ioctl to get it. - Add it to the image, because it works reasonably well and there is no reason not to include it. |
