Before when creating a new inode, we'd set the sb->s_dirt flag, and sometime later the system would write out s_nextid as part of the sb_info. Also on inode sync we would force the sb sync as well. Define the s_nextid as a new partition attribute and set it every time we create a new object. At mount we read it from it's new place. We now never set sb->s_dirt anywhere in exofs. write_super is actually never called. The call to exofs_write_super from exofs_put_super is also removed because the VFS always calls ->sync_fs before calling ->put_super twice. To stay backward-and-forward compatible we also write the old s_nextid in the super_block object at unmount, and support zero length attribute on mount. This also fixes a BUG where in layouts when group_width was not a divisor of EXOFS_SUPER_ID (0x10000) the s_nextid was not read from the device it was written to. Because of the sliding window layout trick, and because the read was always done from the 0 device but the write was done via the raid engine that might slide the device view. Now we read and write through the raid engine. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> |
