[PATCH -next v2] jbd2: use the correct print format
From: Bixuan Cui
Date: Tue Oct 11 2022 - 07:34:09 EST
The print format error was found when using ftrace event:
<...>-1406 [000] .... 23599442.895823: jbd2_end_commit: dev 252,8 transaction -1866216965 sync 0 head -1866217368
<...>-1406 [000] .... 23599442.896299: jbd2_start_commit: dev 252,8 transaction -1866216964 sync 0
Use the correct print format for transaction, head and tid.
Fixes: 879c5e6b7cb4 ('jbd2: convert instrumentation from markers to tracepoints')
