New Revision: 339336
URL: https://svnweb.freebsd.org/changeset/base/339336
Log:
MFC r339076
This has been edited slightly from the version in head. In head, the probe
sections of dadone() were split out into separate functions. In stable/11,
dadone() is still a single function.
So, for stable/11, this describes the change:
sys/cam/scsi/scsi_da.c:
In the DA_CCB_PROBE_DONE case in dadone(), free the data pointer
before returning.

Fix a da(4) driver memory leak for SCSI SMR devices.
In the probe case for SCSI SMR Host Aware or Most Managed drives, be sure
to free allocated memory.
sys/cam/scsi/scsi_da.c:
In dadone_probezone(), free the data pointer before returning.
