current_fs_time() is used for inode timestamps.

Change the signature of the function to take inode pointer instead of superblock as per Linus's suggestion.

Also, move the api under vfs as per the discussion on the thread: https://lkml.org/lkml/2016/6/9/36 . As per Arnd's suggestion on the thread, changing the function name.

current_fs_time() will be deleted after all the references to it are replaced by current_time().

There was a bug reported by kbuild test bot with the change as some of the calls to current_time() were made before the super_block was initialized. Catch these accidental assignments as timespec_trunc() does for wrong granularities. This allows for the function to work right even in these circumstances. But, adds a warning to make the user aware of the bug.

A coccinelle script was used to identify all the current .alloc_inode super_block callbacks that updated inode timestamps. proc filesystem was the only one that was modifying inode times as part of this callback. The series includes a patch to fix that.

Note that timespec_trunc() will also be moved to fs/inode.c in a separate patch when this will need to be revamped for bounds checking purposes.

/* * Snapshotting support.

CURRENT_TIME macro is not appropriate for filesystems as it doesn't use the right granularity for filesystem timestamps. Use current_time() instead.

CURRENT_TIME is also not y2038 safe.

This is also in preparation for the patch that transitions vfs timestamps to use 64 bit time and hence make them y2038 safe. As part of the effort current_time() will be extended to do range checks. Hence, it is necessary for all file system timestamps to use current_time(). Also, current_time() will be transitioned along with vfs to be y2038 safe.

Note that whenever a single call to current_time() is used to change timestamps in different inodes, it is because they share the same time granularity.

current_fs_time() uses struct super_block* as an argument. As per Linus's suggestion, this is changed to take struct inode* as a parameter instead. This is because the function is primarily meant for vfs inode timestamps. Also the function was renamed as per Arnd's suggestion.

Change all calls to current_fs_time() to use the new current_time() function instead. current_fs_time() will be deleted.

jfs uses nanosecond granularity for filesystem timestamps. Only this assignment is not using nanosecond granularity. Use current_time() to get the right granularity.

CURRENT_TIME_SEC is not y2038 safe. current_time() will be transitioned to use 64 bit time along with vfs in a separate patch. There is no plan to transition CURRENT_TIME_SEC to use y2038 safe time interfaces.

current_time() returns timestamps according to the granularities set in the inode's super_block. The granularity check to call current_fs_time() or CURRENT_TIME_SEC is not required.

Use current_time() directly to update inode timestamp. Use timespec_trunc during file system creation, before the first inode is created.

Change signature of helper cifs_all_info_to_fattr since it now needs both super_block and cifs_sb_info.

Note: The inode timestamps read from the server are assumed to have correct granularity and range.

This is in preparation for the change that transitions filesystem timestamps to use 64 bit time and hence make them y2038 safe.

CURRENT_TIME macro will be deleted before merging the aforementioned patch.

Filesystems will use current_time() instead of CURRENT_TIME. Use ktime_get_real_seconds() here as this is not filesystem time. Only the seconds portion of the timestamp is necessary for timezone calculation using server time.

Assume that the difference between server and client times lie in the range INT_MIN..INT_MAX. This is valid because this is the difference between current times between server and client, and the largest timezone difference is in the range of one day.

All cifs timestamps currently use timespec internally. This timestamp can also be transitioned into using timespec64 when all other timestamps for cifs is transitioned to use timespec64.

CURRENT_TIME macro is not appropriate for filesystems as it doesn't use the right granularity for filesystem timestamps. Use current_time() instead.

This is also in preparation for the patch that transitions vfs timestamps to use 64 bit time and hence make them y2038 safe. As part of the effort current_time() will be extended to do range checks. Hence, it is necessary for all file system timestamps to use current_time().

Also change format string for prints so that these are valid when vfs is transitioned to use 64 bit timestamps.

CURRENT_TIME is not y2038 safe.

Use y2038 safe ktime_get_real_seconds() here for timestamps. struct heartbeat_block's hb_seq and deletetion time are already 64 bits wide and accommodate times beyond y2038.

Also use y2038 safe ktime_get_real_ts64() for on disk inode timestamps. These are also wide enough to accommodate time64_t.

/*

boot_time is represented as a struct timespec. struct timespec and CURRENT_TIME are not y2038 safe. Overall, the plan is to use timespec64 and ktime_t for all internal kernel representation of timestamps. CURRENT_TIME will also be removed.

boot_time is used to construct the nfs client boot verifier.

Use ktime_t to represent boot_time and ktime_get_real() for the boot_time value.

Following Trond's request https://lkml.org/lkml/2016/6/9/22 , use ktime_t instead of converting to struct timespec64.

Use higher and lower 32 bit parts of ktime_t for the boot verifier.

Use the lower 32 bit part of ktime_t for the authsys_parms stamp field.

CURRENT_TIME is not y2038 safe. The macro will be deleted and all the references to it will be replaced by ktime_get_* apis.

struct timespec is also not y2038 safe. Retain timespec for timestamp representation here as ceph uses it internally everywhere. These references will be changed to use struct timespec64 in a separate patch.
