Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by: NMartin K.

For each quota type each node has local quota file. In this file it stores changes users have made to disk usage via this node. Once in a while this information is synced to global file (and thus with other nodes) so that limits enforcement at least aproximately works. Global quota files contain all the information about usage and limits. It's mostly handled by the generic VFS code (which implements a trie of structures inside a quota file). We only have to provide functions to convert structures from on-disk format to in-memory one. We also have to provide wrappers for various quota functions starting transactions and acquiring necessary cluster locks before the actual IO is really started.

Add some thin wrappers around ocfs2_insert_extent() for each of the 3 different btree types, ocfs2_inode_insert_extent(), ocfs2_xattr_value_insert_extent() and ocfs2_xattr_tree_insert_extent(). The last is for the xattr index btree, which will be used in a followup patch. All the old callers in file.c etc will call ocfs2_dinode_insert_extent(), while the other two handle the xattr issue. And the init of extent tree are handled by these functions. When storing xattr value which is too large, we will allocate some clusters for it and here ocfs2_extent_list and ocfs2_extent_rec will also be used. In order to re-use the b-tree operation code, a new parameter named "private" is added into ocfs2_extent_tree and it is used to indicate the root of ocfs2_exent_list. The reason is that we can't deduce the root from the buffer_head now. It may be in an inode, an ocfs2_xattr_block or even worse, in any place in an ocfs2_xattr_bucket.

The configfs operations ->make_item() and ->make_group() currently return a new item/group. A return of NULL signifies an error. Because of this, -ENOMEM is the only return code bubbled up the stack. Multiple folks have requested the ability to return specific error codes when these operations fail. This patch adds that ability by changing the ->make_item/group() ops to return ERR_PTR() values. These errors are bubbled up appropriately. NULL returns are changed to -ENOMEM for compatibility. Also updated are the in-kernel users of configfs. This is a rework of reverted commit 11c3b792.

/sys/fs is where we really want file system specific sysfs objects. Ocfs2-tools has been updated to look in /sys/fs/o2cb. We can maintain backwards compatibility with old ocfs2-tools by using a sysfs symlink. After some time (2 years), the symlink can be safely removed.

Currently, o2net connects to a node on hb_up and disconnects on hb_down and net timeout. It disconnects on net timeout is ok, but it should attempt to reconnect back. This is because sometimes nodes get overloaded enough that the network connection breaks but the disk hb does not. And if we get into that situation, we either fence (unnecessarily) or wait for its disk hb to die (and sometimes hang in the process). So in this updated scheme, when the network disconnects, we keep attempting to reconnect till we succeed or we get a disk hb down event. If the other node is really dead, then we will eventually get a node down event. If not, we should be able to connect again and continue.

Currently, when ocfs2 nodes connect via TCP, they advertise their compatibility level. If the versions do not match, two nodes cannot speak to each other and they disconnect. As a result, this provides no forward or backwards compatibility. This patch implements a simple protocol negotiation at the dlm level by introducing a major/minor version number scheme for entities that communicate. Specifically, o2dlm has a major/minor version for interaction with o2dlm on other nodes, and ocfs2 itself has a major/minor version for interacting with the filesystem on other nodes. This will allow rolling upgrades of ocfs2 clusters when changes to the locking or network protocols can be done in a backwards compatible manner. In those cases, only the minor number is changed and the negotatied protocol minor is returned from dlm join. In the far less likely event that a required protocol change makes backwards compatibility impossible, we simply bump the major number.

The meta lock now covers both meta data and data, so this just removes the now-redundant data lock. Combining locks saves us a round of lock mastery per inode and one less lock to ping between nodes during read/write. We don't lose much - since meta locks were always held before a data lock (and at the same level) ordered writeout mode (the default) ensured that flushing for the meta data lock also pushed out data anyways.
