[LU-2786] fsetxattr() doesn't save pool name in stripe data

Mon, 22 Apr 2013 14:53:00 +0000

Setting the stripe data on a file through the fsetxattr() interface fails to save the pool name. Setting the same stripe data through ioctl() works as expected.

The attached C program demonstrates the problem:
