* dlm: Split lock mode and flag constants into a sharable header.Joel Becker2008-01-25
| | | | | | | | | | This allows others to use the DLM constants without being tied to the function API of fs/dlm.

* ocfs2: Rename ocfs2_meta_[un]lockMark Fasheh2008-01-25
| | | | | | | Call this the "inode_lock" now, since it covers both data and meta data. This patch makes no functional changes. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Remove data locksMark Fasheh2008-01-25
| | | | | | | | | | | | | | 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.

* ocfs2: Add data downconvert worker to inode lockMark Fasheh2008-01-25
| | | | | | | | In order to extend inode lock coverage to inode data, we use the same data downconvert worker with only a small modification to only do work for regular files. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Remove mount/unmount votesMark Fasheh2008-01-25
| | | | | | | | | | | | The node maps that are set/unset by these votes are no longer relevant, thus we can remove the mount and umount votes. Since those are the last two remaining votes, we can also remove the entire vote infrastructure. The vote thread has been renamed to the downconvert thread, and the small amount of functionality related to managing it has been moved into fs/ocfs2/dlmglue.c. All references to votes have been removed or updated. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Remove fs dependency on ocfs2_heartbeat moduleMark Fasheh2008-01-25
| | | | | | | | | Now that the dlm exposes domain information to us, we don't need generic node up / node down callbacks. And since the DLM is only telling us when a node goes down unexpectedly, we no longer need to optimize away node down callbacks via the umount map. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2_dlm: Call node eviction callbacks from heartbeat handlerMark Fasheh2008-01-25
| | | | | | | | With this, a dlm client can take advantage of the group protocol in the dlm to get full notification whenever a node within the dlm domain leaves unexpectedly. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| * JFS is missing a memory barrierNick Piggin2008-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | JFS is missing a memory barrier needed to close the critical section before clearing the lock bit. Use lock bitops for this. unlock_page() has a second barrier after clearing the lock, which is required because it checks whether the waitqueue is active without locks. Such a barrier is not required here because the waitqueue spinlock is always taken (something to think about if performance is an issue).

| * JFS: Make sure special inode data is written after journal is flushedDave Kleikamp2008-01-03
| | | | | | | | | | | | | | | | | | This patch makes sure that data that we tried to flush before the journal was completely written actually gets pushed to disk. To avoid duplicating code, moved common code to write_special_inodes(). Signed-off-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com>
| * JFS: clear PAGECACHE_TAG_DIRTY for no-write pagesDave Kleikamp2008-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When JFS decides to drop a dirty metapage, it simply clears the META_dirty bit and leave alone the PG_dirty and PAGECACHE_TAG_DIRTY bits. When such no-write page goes to metapage_writepage(), the `relic' PAGECACHE_TAG_DIRTY tag should be cleared, to prevent pdflush from repeatedly trying to sync them. This is done through set_page_writeback(), so call it should be called in all cases. If no I/O is initiated, end_page_writeback() should be called immediately. This is how __block_write_full_page() does things. Signed-off-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com> CC: Fengguang Wu <wfg@mail.ustc.edu.cn>

This will allow filesystems to directly own and control all of their mount options if they so choose. This interface deals only with option identifiers and strings so it should generic enough for any LSM which may come in the future. Filesystems which pass text mount data around in the kernel (almost all of them) need not currently make use of this interface when dealing with SELinux since it will still parse those strings as it always has. I assume future LSM's would do the same. NFS is the primary FS which does not use text mount data and thus must make use of this interface. An LSM would need to implement these functions only if they had mount time options, such as selinux has context= or fscontext=. If the LSM has no mount time options they could simply not implement and let the dummy ops take care of things. An LSM other than SELinux would need to define new option numbers in security.h and any FS which decides to own there own security options would need to be patched to use this new interface for every possible LSM. This is because it was stated to me very clearly that LSM's should not attempt to understand FS mount data and the burdon to understand security should be in the FS which owns the options.

This patch adds a call to this hook when handling a PTRACE_TRACEME request as well. Currently only one architecture, m32r, implements this hook. When called, it initializes a number of debug trap slots in the ptraced task's thread struct, and it looks to me like this is the right thing to do after a PTRACE_TRACEME request as well, not only after PTRACE_ATTACH. Please correct me if I'm wrong. I want to use this hook on AVR32 to turn the debugging hardware on when a process is actually being debugged and keep it off otherwise. To be able to do this, I need to intercept PTRACE_TRACEME and PTRACE_ATTACH, as well as PTRACE_DETACH and thread exit. The latter two can be handled by existing hooks.

| * | | [GFS2] Allow journal recovery on read-only mountAbhijith Das2008-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows gfs2 to perform journal recovery even if it is mounted read-only. Strictly speaking, a read-only mount should not be writing to the filesystem, but we do this only to perform journal recovery. A read-only mount will fail if we don't recover the dirty journal. Also, when gfs2 is used as a root filesystem, it will be mounted read-only before being mounted read-write during the boot sequence. A failed read-only mount will panic the machine during bootup.
