-Subject: bcachefs: Fix negative timespecs
-MIME-Version: 1.0

-commit a3ed1cc4136df01e74a8b6df8c562db69e752bad upstream.
-
-This fixes two problems in the handling of negative times:
-
- • rem is signed, but the rem * c->sb.nsec_per_time_unit operation
- produced a bogus unsigned result, because s32 * u32 = u32.
-
- • The timespec was not normalized (it could contain more than a
- billion nanoseconds).
-
-For example, { .tv_sec = -14245441, .tv_nsec = 750000000 }, after
-being round tripped through timespec_to_bch2_time and then
-bch2_time_to_timespec would come back as
-{ .tv_sec = -14245440, .tv_nsec = 4044967296 } (more than 4 billion
-nanoseconds).
