32 bit systems using 'struct timeval' will break in the year 2038, so we modify the code appropriately.
This patch replaces the use of struct timeval and do_gettimeofday() with ktime_get_real_seconds() which returns a 64 bit value which is safer than struct timeval. This patch also replaces u32 time storing variables with u64 variables to store the 64 bit seconds value returned by ktime_get_real_seconds() Signed-off-by: Amitoj Kaur Chawla <[email protected]> --- Changes in v2: -Converted u32 type to u64 type drivers/scsi/bfa/bfa_fcpim.c | 2 +- drivers/scsi/bfa/bfa_fcpim.h | 4 ++-- drivers/scsi/bfa/bfad_bsg.c | 6 +++--- 3 files changed, 6 insertions(+), 6 deletions(-) diff --git a/drivers/scsi/bfa/bfa_fcpim.c b/drivers/scsi/bfa/bfa_fcpim.c index d7385d1..224db4e 100644 --- a/drivers/scsi/bfa/bfa_fcpim.c +++ b/drivers/scsi/bfa/bfa_fcpim.c @@ -468,7 +468,7 @@ bfa_ioim_profile_start(struct bfa_ioim_s *ioim) } bfa_status_t -bfa_fcpim_profile_on(struct bfa_s *bfa, u32 time) +bfa_fcpim_profile_on(struct bfa_s *bfa, u64 time) { struct bfa_itnim_s *itnim; struct bfa_fcpim_s *fcpim = BFA_FCPIM(bfa); diff --git a/drivers/scsi/bfa/bfa_fcpim.h b/drivers/scsi/bfa/bfa_fcpim.h index e693af6..274e3af 100644 --- a/drivers/scsi/bfa/bfa_fcpim.h +++ b/drivers/scsi/bfa/bfa_fcpim.h @@ -135,7 +135,7 @@ struct bfa_fcpim_s { struct bfa_fcpim_del_itn_stats_s del_itn_stats; bfa_boolean_t ioredirect; bfa_boolean_t io_profile; - u32 io_profile_start_time; + u64 io_profile_start_time; bfa_fcpim_profile_t profile_comp; bfa_fcpim_profile_t profile_start; }; @@ -309,7 +309,7 @@ bfa_status_t bfa_fcpim_port_iostats(struct bfa_s *bfa, struct bfa_itnim_iostats_s *stats, u8 lp_tag); void bfa_fcpim_add_stats(struct bfa_itnim_iostats_s *fcpim_stats, struct bfa_itnim_iostats_s *itnim_stats); -bfa_status_t bfa_fcpim_profile_on(struct bfa_s *bfa, u32 time); +bfa_status_t bfa_fcpim_profile_on(struct bfa_s *bfa, u64 time); bfa_status_t bfa_fcpim_profile_off(struct bfa_s *bfa); #define bfa_fcpim_ioredirect_enabled(__bfa) \ diff --git a/drivers/scsi/bfa/bfad_bsg.c b/drivers/scsi/bfa/bfad_bsg.c index 023b9d4..92f5b0f 100644 --- a/drivers/scsi/bfa/bfad_bsg.c +++ b/drivers/scsi/bfa/bfad_bsg.c @@ -15,6 +15,7 @@ * General Public License for more details. */ +#include <linux/ktime.h> #include <linux/uaccess.h> #include "bfad_drv.h" #include "bfad_im.h" @@ -2093,13 +2094,12 @@ bfad_iocmd_fcpim_cfg_profile(struct bfad_s *bfad, void *cmd, unsigned int v_cmd) { struct bfa_bsg_fcpim_profile_s *iocmd = (struct bfa_bsg_fcpim_profile_s *)cmd; - struct timeval tv; unsigned long flags; - do_gettimeofday(&tv); spin_lock_irqsave(&bfad->bfad_lock, flags); if (v_cmd == IOCMD_FCPIM_PROFILE_ON) - iocmd->status = bfa_fcpim_profile_on(&bfad->bfa, tv.tv_sec); + iocmd->status = bfa_fcpim_profile_on(&bfad->bfa, + ktime_get_real_seconds()); else if (v_cmd == IOCMD_FCPIM_PROFILE_OFF) iocmd->status = bfa_fcpim_profile_off(&bfad->bfa); spin_unlock_irqrestore(&bfad->bfad_lock, flags); -- 1.9.1 _______________________________________________ Y2038 mailing list [email protected] https://lists.linaro.org/mailman/listinfo/y2038
