It appears that roughly half the filesystems in this series don't touch the i_atime in this case. And the other half do. Which is correct? Did they incorrectly set i_atime instead of i_ctime?

POSIX says: "Upon successful completion, where nbyte is greater than 0, write() shall mark for update the last data modification and last file status change timestamps of the file..." Add the missing ctime update. Signed-off-by: Jeff Layton <jlayton@kernel.org> --- fs/smb/client/file.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
