* [S390] vdso: use ntp adjusted clock multiplierHendrik Brueckner2010-04-227-12/+15
| | | | | | | | | | | | | | | | | | Commit "timekeeping: Fix clock_gettime vsyscall time warp" (0696b711e) introduced the new parameter "mult" to update_vsyscall(). This parameter contains the internal NTP adjusted clock multiplier. The s390x vdso did not use this adjusted multiplier. Instead, it used the constant clock multiplier for gettimeofday() and clock_gettime() variants. This may result in observable time warps as explained in commit 0696b711e. Make the NTP adjusted clock multiplier available to the s390x vdso implementation and use it for time calculations.

This gets rid of a quota warning about writes before quota is turned on for systems with ext4 root filesystem. Currently there's no way to legally solve this because /etc/mtab has to be written before quota is turned on on most systems. Signed-off-by: Jan Kara <jack@suse.cz>
