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

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

The following series of patches attempts to detach metadata I/O from struct inode. They are currently tied together pretty tightly. Metadata reads happen via the ocfs2_read_blocks() functions, writes via both jbd2 and ocfs2_write_blocks(). - Each inode has a cache of associated metadata blocks stored on its ip_metadata_cache member. The ocfs2_read/write_blocks() functions take a struct
