2008-07-26[PATCH] sanitize ->permission() prototypeAl Viro
* kill nameidata * argument; map the 3 bits in ->flags anybody cares about to new MAY_... ones and pass with the mask. * kill redundant gfs2_iop_permission() * sanitize ecryptfs_permission() * fix remaining places where ->permission() instances might barf on new MAY_... found in mask.

2008-07-26SL*B: drop kmem cache argument from constructorAlexey Dobriyan
Kmem cache passed to constructor is only needed for constructors that are themselves multiplexeres. Nobody uses this "feature", nor does anybody uses passed kmem cache in non-trivial way, so pass only pointer to object.

2008-07-17configfs: Allow ->make_item() and ->make_group() to return detailed errors.Joel Becker
The configfs operations ->make_item() and ->make_group() currently return a new item/group. A return of NULL signifies an error. Because of this, -ENOMEM is the only return code bubbled up the stack. Multiple folks have requested the ability to return specific error codes when these operations fail. This patch adds that ability by changing the ->make_item/group() ops to return ERR_PTR() values. These errors are bubbled up appropriately. NULL returns are changed to -ENOMEM for compatibility. Also updated are the in-kernel users of configfs. This is a rework of reverted commit 11c3b79218390a139f2d474ee1e983a672d5839a. Signed-off-by: Joel Becker <joel.becker@oracle.com>

2008-07-16[PATCH] ocfs2: fix oops in mmap_truncate testingColy Li
This patch fixes a mmap_truncate bug which was found by ocfs2 test suite. In an ocfs2 cluster more than 1 node, run program mmap_truncate, which races mmap writes and truncates from multiple processes. While the test is running, a stat from another node forces writeout, causing an oops in ocfs2_get_block() because it sees a buffer to write which isn't allocated. This patch fixed the bug by clear dirty and uptodate bits in buffer, leave the buffer unmapped and return. Fix is suggested by Mark Fasheh, and I code up the patch.

2008-07-14ocfs2: Don't snprintf() without a format.Joel Becker
Some system files are per-slot. Their names include the slot number. ocfs2_sprintf_system_inode_name() uses the system inode definitions to fill in the slot number with snprintf(). For global system files, there is no node number, and the name was printed as a format with no arguments. -Wformat-nonliteral and -Wformat-security don't like this. Instead, use a static "%s" format and the name as the argument. Signed-off-by: Joel Becker <joel.becker@oracle.com>

2008-07-10ocfs2: Fix flags in ocfs2_file_lockMark Fasheh
The stack-glue merge changed the way we use flags in dlmglue in that we now use the fs/dlm equivalents. Unfortunately, a merge error left the new flock code only partially updated. This took a while to show up though, because the lock level constants are actually identical between o2dlm and fs/dlm.

/sys/fs is where we really want file system specific sysfs objects. Ocfs2-tools has been updated to look in /sys/fs/o2cb. We can maintain backwards compatibility with old ocfs2-tools by using a sysfs symlink. After some time (2 years), the symlink can be safely removed.

2008-04-18ocfs2: Reconnect after idle time out.Tao Ma
Currently, o2net connects to a node on hb_up and disconnects on hb_down and net timeout. It disconnects on net timeout is ok, but it should attempt to reconnect back. This is because sometimes nodes get overloaded enough that the network connection breaks but the disk hb does not. And if we get into that situation, we either fence (unnecessarily) or wait for its disk hb to die (and sometimes hang in the process). So in this updated scheme, when the network disconnects, we keep attempting to reconnect till we succeed or we get a disk hb down event. If the other node is really dead, then we will eventually get a node down event. If not, we should be able to connect again and continue.
