[PATCH 0/3] Btrfs: add IO error device stats
The goal is to detect when drives start to get an increased error rate,
when drives should be replaced soon. Therefore statistic counters are
added that count IO errors (read, write and flush). Additionally, the
software detected errors like checksum errors and corrupted blocks are
counted.
An ioctl interface is added to get the device statistic counters.
A second ioctl is added to atomically get

[PATCH v5 0/3] Btrfs: add IO error device stats
Changes v1-v2:
- Remove restriction that BTRFS_IOC_GET_DEVICE_STATS is a privileged
operation
- Cast u64 to unsigned long long for printf()
Changes v2-v3:
- Rebased on Chris'' current master
Changes v3-v4:
- Add padding at end of ioctl structure
Changes v4-v5:
- The statistic members in the ioctl are now organized as an array of
64 bit values. Symbolic names for the array indexes

[patch 00/65] Error handling patchset v3
Hi all -
Here''s my current error handling patchset, against 3.1-rc8. Almost all of
this patchset is preparing for actual error handling. Before we start in
on that work, I''m trying to reduce the surface we need to worry about. It
turns out that there is a ton of code that returns an error code but never
actually reports an error.
The patchset has grown to 65 patches. 46 of them
