[PATCH] ufs2: more correct work with time
This patch corrects work with time in UFS2 case. 1) According to UFS2 disk layout modification/access and so on "time" should be hold in two variables one 64bit for seconds and another 32bit for nanoseconds, at now for some unknown reason we suppose that "inode time" holds in three variables 32bit for seconds, 32bit for milliseconds and 32bit for nanoseconds. 2) We set amount of nanoseconds in "VFS inode" to 0 during read, instead of getting values from "on disk inode"(this should close http://bugzilla.kernel.org/show_bug.cgi?id=7991).
