Finally! For a very long time, our MST helpers have had one very annoying issue: They don't know how to reprobe the topology state when coming out of suspend. This means that if a user has a machine connected to an MST topology and decides to suspend their machine, we lose all topology changes that happened during that period. That can be a big problem if the machine was connected to a

Even though we allocate more, we should be updating inode i_size as per the arguments passed Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> --- Changes from V1: We should update i_size only if actual_len and cur_offset are both larger than i_size. Otherwise if actual_len is < i_size and cur_offset > i_size we may end up setting wrong i_size value

This is the large series for adding MST suspend/resume reprobing that I've been working on for quite a while now. In addition, I: - Refactored and cleaned up any code I ended up digging through in the process of understanding how some parts of these helpers worked. - Added some debugging tools along the way that I ended up needing to figure out some issues in my own code Note that

Hello, I want to throw this out here now that I''ve got most of the heavy lifting done for this code to make sure what I''m doing is ok for now. I''ve added an ORPHAN_DIR item key to have a hidden dir per root. Right now it just does it for whatever the default root is on mount, but I''m going to fix that to do the orphan dir check/creation on lookup of a

Hello, I work at SmarctJog.com, we have here some patches on IceCast for performance and reliability, these are mostly client/connection/source cleanups (a slave merge is underway, and some more good stuff (c)), but we'd like this to be merged in before the list gets any longer. Please find attached a list of our patches with a short desc: This one is actually not from us/me, it was found

fallocate(2) may allocate large number of file extents, so it''s not good to do it in a single transaction. This patch make fallocate(2) start a new transaction for each file extents it allocates. Signed-off-by: Yan Zheng <zheng.yan@oracle.com> --- diff -urp 6/fs/btrfs/inode.c 7/fs/btrfs/inode.c --- 6/fs/btrfs/inode.c 2009-11-02 10:47:16.106890431 +0800 +++ 7/fs/btrfs/inode.c

This patch finally gives us full proper -ENOSPC handling for btrfs. Now whenever you do a btrfs_start_transaction, you must specify the number of items you are planning to add/delete/modify. The worst case number of blocks that could be modified by changing that number of items will be calculated and checked against the amount of free space in the space_info where the root you are modifying

ext2 & ext3 lists, Attatched is a patch that allows ext2 and ext3 to link correctly when the kernel is configured with a large NR_CPUS. We do have an immediate need for this patch. Any opinions on this? The per-cpu lists are causing the kmalloc to fail due to allocating more than the max. thanks mh -- Martin Hicks Wild Open Source Inc. mort@wildopensource.com

If we have particularly full nodes, we could call btrfs_node_blockptr up to 32 times, which is 32 pairs of kmap/kunmap, which _sucks_. So go ahead and map the extent buffer while we look for readahead targets.
