[01/21] fs: Replace CURRENT_TIME_SEC with current_fs_time()

Commit Message

Deepa Dinamani June 9, 2016, 5:04 a.m. UTC

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

current_fs_time() will also be extended to use superblock
range checking parameters when range checking is introduced.

This works because alloc_super() fills in the the s_time_gran
in super block to NSEC_PER_SEC.

Also note that filesystem specific times like the birthtime,
creation time that were using same interfaces to obtain time
retain same logistics.

You create line longer than 80 characters for affs and reiserfs. Please
wrap those lines properly. Other than that feel free to add:

OMFS parts look sane, thanks.

No, please do *NOT* do things like that.

These kind of mechanical patches should

 (a) be as mechanical as possible (and see elsewhere about why I think
'sb' should be 'inode' and the patch should have been 95% automated
with a trivial script thanks to that change)

 (b) be made as easy to verify visually as possible.

That (b) means that a conversion should *not* add whitespace fixups or
add other non-mechanical cleanups, because it's a *lot* easier to see
that a conversion like

-       inode->i_mtime = inode->i_ctime = CURRENT_TIME_SEC;
+       inode->i_mtime = inode->i_ctime = current_fs_time(inode);

makes no other changes, but if you start doing line-splitting or other
transformations (add new variables etc to get at 'sb'), suddenly you
have to verify the patch at a completely different level.

In other words, it's actually really important to make these kinds of
bulk changes be very very obvious. Including to the point of making
them visually easier to scan as a patch by not making any other
changes.

Thanks for the guidelines.
Only patches 1 and 4 are mechanical.
All others need some kind of inspection/ verification.
I will keep these in mind for updating 1 and 4.

one question:

In an earlier version, you had a small optimization to
use ktime_get_real_seconds() instead of current_kernel_time()
when the granularity is seconds.

Do you still plan to send that one, or did you decide we don't
need it?

I was actually planning to use get_seconds() instead of current_kernel_time().
And, transition both along with vfs to y2038 safe apis.
Difference between ktime_get_real_seconds() and current_kernel_time64()
is not much because they both require sequence counter.

It didn't make sense to me to optimize current_fs_time() for seconds
only, and not optimize for 1ns granularity also.
I plan to make changes to the function depending on how we end up
using timespec_trunc()
after the addition of range checking.

Thanks for the guidance on inclusion of reviewers. I'll follow this
approach when I post v2 of the series.

Ah, you are right: adding another check for second granularity would
probably cost more than it would save, since we already don't calculate
the exact nanoseconds but just use the timestamp of the last timer
tick.

Makes sense. I guess we can skip the range checking for
current_fs_time() if we end up not allowing writable mounts on
file systems that cannot represent the current time, but we
do want the range checking for the other users of
timespec_trunc().
