* ocfs2: reserve xattr block for new directory with inline dataTiger Yang2009-03-121-0/+4
| | | | | | | | | | If this is a new directory with inline data, we choose to reserve the entire inline area for directory contents and force an external xattr block.

* ocfs2: set gap to seperate entry and value when xattr in bucketTiger Yang2009-02-261-8/+10
| | | | | | | | | | This patch set a gap (4 bytes) between xattr entry and name/value when xattr in bucket. This gap use to seperate entry and name/value when a bucket is full.

* ocfs2: lock the metaecc process for xattr bucketTao Ma2009-02-263-0/+8
| | | | | | | | | | | For other metadata in ocfs2, metaecc is checked in ocfs2_read_blocks with io_mutex held. While for xattr bucket, it is calculated by the whole buckets. So we have to add a spin_lock to prevent multiple processes calculating metaecc.

* ocfs2/dlm: Make dlm_assert_master_handler() kill itself instead of the asserterSunil Mushran2009-02-261-6/+6
| | | | | | | | | | | | | | In dlm_assert_master_handler(), if we get an incorrect assert master from a node that, we reply with EINVAL asking the asserter to die. The problem is that an assert is sent after so many hoops, it is invariably the node that thinks the asserter is wrong, is actually wrong. So instead of killing the asserter, this patch kills the assertee. This patch papers over a race that is still being addressed.

| | | | | | | | | | | | | | Mainline commit d4f7e650e55af6b235871126f747da88600e8040 attempts to delay the dlm_thread from sending the drop ref message if the lockres is being migrated. The problem is that we make the dlm_thread wait for the migration to complete. This causes a deadlock as dlm_thread also participates in the lockres migration process.

* jbd2: Avoid possible NULL dereference in jbd2_journal_begin_ordered_truncate()Jan Kara2009-02-101-2/+4
| | | | | | | | | | | | | | | | | | | | | If we race with commit code setting i_transaction to NULL, we could possibly dereference it. Proper locking requires the journal pointer (to access journal->j_list_lock), which we don't have. So we have to change the prototype of the function so that filesystem passes us the journal pointer. Also add a more detailed comment about why the function jbd2_journal_begin_ordered_truncate() does what it does and how it should be used.

* ocfs2: Wakeup the downconvert thread after a successful cancel convertSunil Mushran2009-02-021-0/+4
| | | | | | | | | | | | | | | When two nodes holding PR locks on a resource concurrently attempt to upconvert the locks to EX, the master sends a BAST to one of the nodes. This message tells that node to first cancel convert the upconvert request, followed by downconvert to a NL. Only when this lock is downconverted to NL, can the master upconvert the first node's lock to EX. While the fs was doing the cancel convert, it was forgetting to wake up the dc thread after a successful cancel, leading to a deadlock.

| | | | | | | | | | | | In ocfs2_xattr_value_truncate, we may call b-tree codes which will extend the journal transaction. It has a potential problem that it may let the already-accessed-but-not-dirtied buffers gone. So we'd better access the bucket after we call ocfs2_xattr_value_truncate. And as for the root buffer for the xattr value, b-tree code will acess and dirty it, so we don't need to worry about it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dlm_get_lock_resource() is supposed to return a lock resource with a proper master. If multiple concurrent threads attempt to lookup the lockres for the same lockid while the lock mastery in underway, one or more threads are likely to return a lockres without a proper master. This patch makes the threads wait in dlm_get_lock_resource() while the mastery is underway, ensuring all threads return the lockres with a proper master. This issue is known to be limited to users using the flock() syscall. For all other fs operations, the ocfs2 dlmglue layer serializes the dlm op for each lockid.

| * ocfs2: Use ocfs2_xattr_value_buf in ocfs2_xattr_set_entry().Joel Becker2009-01-051-24/+29
| | | | | | | | | | | | | | | | | | | | ocfs2_xattr_set_entry is the function that knows what type of block it is setting into. This is what we wanted from ocfs2_xattr_value_buf. Plus, moving the value buf up into ocfs2_xattr_set_entry() allows us to pass it into ocfs2_xattr_set_value_outside() and ocfs2_xattr_cleanup().

| * ocfs2: Pass value buf to ocfs2_xattr_update_entry().Joel Becker2009-01-051-4/+6
| | | | | | | | | | | | | | | | | | ocfs2_xattr_update_entry() updates the entry portion of an xattr buffer. This can be part of multiple metadata block types, so pass the buffer in via an ocfs2_xattr_value_buf.

| * ocfs2: Pass ocfs2_xattr_value_buf into ocfs2_xattr_value_truncate().Joel Becker2009-01-051-32/+34
| | | | | | | | | | | | | | | | | | The callers of ocfs2_xattr_value_truncate() now pass in ocfs2_xattr_value_bufs. These callers are the ones that calculated the xv location, so they are the right starting point. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>

| | | | | | | | | | | | | | | | | | Place an ocfs2_xattr_value_buf in ocfs2_xattr_value_truncate() and pass it down to ocfs2_xattr_shrink_size(). We can also pass it into ocfs2_xattr_extend_allocation(), replacing its ocfs2_xattr_value_buf. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
