The cfs_duration_sec() converts a relative jiffies value into seconds, and returns that number as a time_t. We know that a 32-bit type is enough here, because the result is order of magnitudes smaller than the difference in jiffies that is also expressed as a 'long', so we can safely replace the time_t type with long as well.

This ioctl function passes a 64-bit time argument but then performs a computation with a 32-bit get_seconds() value. In order to avoid overflow here, this changes the code to use 64-bit math and ktime_get_real_seconds(). Signed-off-by:

The lnet_eq_wait_locked tries to wait for time to pass or an event to wake up the wait queue. The entire logic seems to be a very elaborate reimplementation of wait_event(). I'm not trying to clean up the entire logic here, but this at least gets rid of the multi-way conversion between miliseconds, timeval and jiffies. Signed-off-by:

The rq_at_index member of ptlrpc_request is incorrectly declared as time_t, when it is only used as an index into an array, and assigned from a __u32 variable. This changes the type to u32, so we can kill off another use of time_t. Signed-off-by:

process_param2_config() tries to print how much time has passed across a call_usermodehelper() function, and uses struct timeval for that. We want to remove this structure, so this is better expressed in terms of ktime_t and ktime_us_delta(). Signed-off-by:

The l_last_activity struct member is used to keep track lock hold times, and it is printed for debugging purposes. For the elapsed time, we can use 'long' here, but it's better to use time64_t for storing the real time to avoid an overflow in 2038. Signed-off-by:

Some lustre debugfs files contain the current time. Make sure we use a format here that does not overflow in 2038. Signed-off-by:

The lustre tracefile has a timestamp defined as __u32 ph_sec; __u64 ph_usec; which seems completely backwards, as the microsecond portion of a time stamp will always fit into a __u32 value, while the second portion will overflow in 2038 or 2106 (in case of unsigned seconds). Changing this would unfortunately change the format in an incompatible way, breaking all existing user space tools that access the data. This uses ktime_get_real_ts64() to replace the insufficient do_gettimeofday() and then truncates the seconds portion to an u32 type, along with comments to explain the result. A possible alternative would be the use of ktime_get_ts64() to read a monotonic timestamp that never overflows, but this would trigger a check in user space 'hdr->ph_sec < (1 << 30)' that attempts to ensure that the values are within a reasonable range.

We want to get rid of all uses of time_t, and it turns out that obd.h contains a bunch of them that are completely unused. This removes those structures, along with a couple of other structures and functions in the same file that also turned out to be unused. Signed-off-by:

Lustre has 64-bit timestamps in its network data structures, but on 32 bit systems, it converts them directly into time_t, which is 32 bit wide. This changes the code to use 64-bit time stamps for files. The Linux VFS code still uses time_t though, and will be changed in a separate patch series. Signed-off-by:

The recently introduced lnet_peer_set_alive() function uses get_seconds() to read the current time into a shared variable, but all other uses of that variable compare it to jiffies values. This changes the current use to jiffies as well for consistency. Signed-off-by:

STAGING_RDMA was failing to build when INFINIBAND was set to 'm' and STAGING_RDMA was set to 'y'. Making this a tristate properly inherits the 'm' from the INFINIBAND setting. Reviewed-by:

hfi1_rc_hdrerr() stores the result of be32_to_cpu() into opcode, which is a local variable declared as u8. Later this variable is used in a 24-bit logical right shift, which makes clang complains (when building an allmodconfig kernel with LLVMLinux patches): drivers/staging/rdma/hfi1/rc.c:2399:9: warning: shift count >= width of type [-Wshift-count-overflow] opcode >>= 24; ^ ~~ All of this lead to the point that opcode may have been designed to be a 32-bit integer instead of an 8-bit one. Therefore make this variable u32. Signed-off-by:Nicolas Iooss <nicolas.iooss_linux@m4x.org> Acked-by:
