similar to: [PATCH] ocfs2: free allocated clusters if error occurs after ocfs2_claim_clusters

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

This patch is based on ocfs2-free-allocated-clusters-if-error-occurs- after-ocfs2_claim_clusters.patch. https://oss.oracle.com/pipermail/ocfs2-devel/2013-November/009461.html We should note down num of bits to be freed, so as to update i_used correspondingly after clearing those bits in bitmap.

This set of patches includes a few dlm related fixes from Kurt, and a small, trivial cleanup by Adrian. Also included are three disk allocation patches by me - two fixes and one incremental improvement in our allocation strategy. These have been around since early June, so I think they've had enough testing that they can go upstream. Please pull from 'upstream-linus' branch of

In ocfs2_block_group_clear_bits, when num_bits != bits_cleared, it just log an error message without setting EROFS. The code is below: /* * If encountered, it means we are clearing bits multiple times. While * we are handling the case, we still need to be alerted to its * occurrence. Hence, marking it as an ERROR and not NOTICE. */ if (num_bits != bits_cleared) { mlog(ML_ERROR,

Hi All, Here is the latest version of vhost-blk implementation. Major difference from my previous implementation is that, I now merge all contiguous requests (both read and write), before submitting them. This significantly improved IO performance. I am still collecting performance numbers, I will be posting in next few days. Comments ? Todo: - Address hch's comments on annontations -

We keep hitting bugs in the tree log replay because btrfs_remove_free_space doesn''t account for some corner case. So add a bunch of tests to try and fully test btrfs_remove_free_space since the only time it is called is during tree log replay. These tests all finish successfully, so as we find more of these bugs we need to add to these tests to make sure we don''t regress in

Currently ocfs2_start_trans/ocfs2_commit_trans are in lock_page/unlock_page. This may cause dead lock. Here is the situation: write -> lock_page -> ocfs2_start_trans -> ocfs2_commit_trans -> unlock_page ocfs2_start_trans/ocfs2_commit_trans calls jbd2_journal_start/jbd2_journal_stop which may also call lock_page. So if the page operated is unfortunately the same with the page to be

What we were doing before was to ask for the current window size as the maximum allocation. This had the effect of limiting the amount of allocation we could get for the local alloc during times when the window size was shrunk due to fragmentation. In some cases, that could actually *increase* fragmentation by artificially limiting the number of bits we can accept. So while we still want to ask

From: "Xiaowei.Hu" <xiaowei.hu at oracle.com> ocfs2_block_group_alloc_discontig() disables chain relink by setting ac->ac_allow_chain_relink = 0 because it grabs clusters from multiple cluster groups. It doesn't keep the credits for all chain relink,but ocfs2_claim_suballoc_bits overrides this in this call trace:

ocfs2 currently uses the Journaled Block Device (JBD) for its journaling. This is a very stable and tested codebase. However, JBD is limited by architecture to 32bit block numbers. This means an ocfs2 filesystem is limited to 2^32 blocks. With a 4K blocksize, that's 16TB. People want larger volumes. Fortunately, there is now JBD2. JBD2 adds 64bit block number support and some other

In ocfs2_expand_inline_dir, we calculate whether we need 1 extra cluster if we can't store the dx inline the root and save it in dx_alloc. So add it when we call ocfs2_reserve_clusters.

Hi, Just something I don't understand: data <- data.frame(V1=c(1:12),F1=c(rep("a",4),rep("b",4),rep("c",4))) data_ac <- data[which(data$F1 !="b"), ] levels(data_ac$F1) Why the level "b" is always present ? thanks Tristan, R 2.0.1 for Linux Fedora 3 -- ------------------------------------------------------------ Tristan
