Hi,
since Linux 3.6 there is an BLKPG (sub-)ioctl to tell the kernel that
partition size has changed, e.g. used by "partx -u". With strace 4.10
this is dumped as
ioctl(3, BLKPG, {0x3 /* BLKPG_??? */, flags=0, datalen=152, {start=1048576,
length=42948624384, pno=1, devname="", volname=""}}) = 0
/usr/include/linux/blkpg.h:#define BLKPG_RESIZE_PARTITION 3
I propose to add this to strace for completeness.
Thanks,
