            Bug ID: 238343
           Summary: [FEATURE REQUEST] auto run trim for swap devices
                    before swapon
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: rozhuk.im at gmail.com

We have trim command that can send TRIM for device/partition/file.
SWAP partitions have no fs and never get TRIM command on "data delete", this
may decrease some SSD~s performance.

trim command may be executed before swapon (after dumpon) to fix this.
