Hi Linus,
This pull request contains the core block changes for 5.5. Due to more
granular branches, this one is small and will be followed with other
core branches that add specific features. I meant to just have a core
and drivers branch, but external dependencies we ended up adding a few
more that are also core. For this request, the changes are:
- Fixes and improvements for the zoned device support (Ajay, Damien)
- sed-opal table writing and datastore UID (Revanth)
- blk-cgroup (and bfq) blk-cgroup stat fixes (Tejun)
- Improvements to the block stats tracking (Pavel)
- Fix for overruning sysfs buffer for large number of CPUs (Ming)
- Optimization for small IO (Ming, Christoph)
- Fix typo in RWH lifetime hint (Eugene)
- Dead code removal and documentation (Bart)
- Reduction in memory usage for queue and tag set (Bart)
- Kerneldoc header documentation (André)
- Device/partition revalidation fixes (Jan)
- Stats tracking for flush requests (Konstantin)
- Various other little fixes here and there (et al)
Please pull!
