Updated blktrace packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 6.
The blktrace packages contain a number of utilities to record the I/O trace information for the kernel to user space, and utilities to analyze and view the trace information.
- Prior to this update, the blkparse code contained a misprint. As a result, blkparse used the wrong variable when printing the PC Writes Completed. This update modifies the code so that blkparse now prints the correct value for PC Writes Completed.
- This update adds FLUSH/FUA support to blktrace.
All blktrace users are advised to upgrade to these updated packages, which fix this bug and add this enhancement.
