Looking at this block of code http://src.illumos.org/source/xref/illumos-gate/ usr/src/uts/common/fs/zfs/zfs_vnops.c#4187 I see code to set up an sa_bulk_attr_t object, I see code to set up mtime and ctime values, but I do not see code to actually apply the attributes... I would expect there to be a call to sa_bulk_update(), there is such a call in zfs_write() for instance. mmap_write.c [Magnifier] - demo (1.42 KB) Andriy Gapon, 2015-11-11 01:53 PM Reviewed by: Matthew Ahrens Reviewed by: Prashanth Sreenivasa Reviewed by: Dan McDonald Approved by: Gordon Ross Author: Andriy Gapon Modified: Directory Properties: head/sys/cddl/contrib/opensolaris/ (props changed)
