eugen ed557b0b0d trim(8): emit more user-friendly error message in verbose mode. ... If underlying driver provides no TRIM/UNMAP support and operation fails due to this reason, state it clearly in verbose mode (default) instead of writing standard message that may be too cryptic for a user: trim: ioctl(DIOCGDELETE) failed: nda0: Operation not supported Now it would write: trim: nda0: TRIM/UNMAP not supported by driver But still use previous format including errno value for quiet mode. Small candelete() function borrowed from diskinfo(8) code. This function was committed by Alan Somers <asomers@FreeBSD.org>, so give him some credit. Reported by: chuck		2019-03-15 14:42:23 +00:00
