SubjectWrong atime on recent kernels
Hello,

I see some strange file modification times recently. It seems to
me that in some situations, kernel allows to set nanoseconds part of
file access, modification or change time to 100000000 ns. Problem seems
to be in some generic part of kernel because I see it on several
different filesysytems (ext4 and nilf2). These is I've got during my
testing on kernel 2.6.32-tip-08309-gad8e75a.
File: `./Documentation/dvb/contributors.txt'
Size: 3035 Blocks: 8 IO Block: 4096 regular file
Device: fe04h/65028d Inode: 818 Links: 1
Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root)
Access: 2009-12-14 10:29:04.1000000000 +0100
Modify: 2009-12-14 10:29:04.1000000000 +0100
Change: 2009-12-14 10:29:04.1000000000 +0100
See that all times of that file ends with 1e6 nanoseconds.
