similar to: [PATCH V3 RESENT] ocfs2: lighten up allocate transaction

In normal tree rotation left process, we will never touch the tree branch above subtree_index and ocfs2_extend_rotate_transaction doesn't reserve the credits for them either. But when we want to delete the rightmost extent block, we have to update the rightmost records for all the rightmost branch(See ocfs2_update_edge_lengths), so we have to allocate extra credits for them. What's more,

From: Zach Brown <zab@zabbo.net> ocfs2''s .aio_read and .aio_write methods are changed to take iov_iter and pass it to generic functions. Wrappers are made to pack the iovecs into iters and call these new functions.

Provide a splice_read stub for ocfs2. This emits trace lines and does an atime lock/update before calling filemap_splice_read(). Splicing from direct I/O is handled by the caller. A couple of new tracepoints are added for this purpose. Signed-off-by: David Howells <dhowells at redhat.com> cc: Christoph Hellwig <hch at lst.de> cc: Al Viro <viro at zeniv.linux.org.uk> cc: Jens

In ocfs2_add_branch, we use the rightmost rec of the leaf extent block to generate the e_cpos for the new added branch. In the most case, it is OK but if there is a gap between the the root(or branch) 's rightmost rec and the leaf, it will cause kernel panic if we insert some clusters in it. The message is something like: (7445,1):ocfs2_insert_at_leaf:3775 ERROR: bug expression:

From: Zongxun Wang <wangzongxun at huawei.com> Even if using the same jbd2 handle, we cannot rollback a transaction. So once some error occurs after successfully allocating clusters, the allocated clusters will never be used and it means they are lost. For example, call ocfs2_claim_clusters successfully when expanding a file, but failed in ocfs2_insert_extent. So we need free the allocated

Fix "h_buffer_credits<0" assert failure during truncate. The bug occurs when the "i_blocks" count in the file's inode overflows past 2^31. That works fine most of the time, because i_blocks is an unsigned long, and should go up to 2^32; but there's a place in truncate where ext3 calculates the size of the next transaction chunk for the delete, and that mistakenly

Modification from V2 to V3: Use a more pefect code suggested by Joel. Thank Joel for it. In ocfs2/xattr, we must make sure the xattrs which have the same hash value exist in the same bucket so that the search schema can work. But in the old implementation, when we want to extend a bucket, we just move half number of xattrs to the new bucket. This works in most cases, but if we are lucky enough we

This fixes the "i_blocks went wrong when the disk filled up" problem. In ext3_new_block() we increment i_blocks early, so the quota operation can be performed outside lock_super(). But if the block allocation ends up failing, we forget to undo the allocation. This is not a serious bug, and probably does not warrant an upgrade for production machines. Its effects are: 1) errors are
