Despite my earlier careful search, there was a recursive lock left in the deallocation code. This removes it. It also should speed up deallocation be reducing the number of locking operations which take place by using two "try lock" operations on the two locks involved in inode deallocation which allows us to grab the locks out of order (compared with NFS which grabs the inode lock first and the iopen lock later). It is ok for us to fail while doing this since if it does fail it means that someone else is still using the inode and thus it wouldn't be possible to deallocate anyway. This fixes the bug reported to me by Rob Kenna. Cc: Rob Kenna <rkenna@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This patch changes the last user of recursive locking so that it no longer needs this feature and removes it from the glock layer. This makes the glock code a lot simpler and easier to understand. Its also a prerequsite to adding support for the AOP_TRUNCATED_PAGE return code (or at least it is if you don't want your brain to melt in the process) I've left in a couple of checks just in case there is some place else in the code which is still using this feature that I didn't spot yet, but they can probably be removed long term.

This patch addresses a flaw in LSM, where there is no mediation of readv() and writev() in for 32-bit compatible apps using a 64-bit kernel. This bug was discovered and fixed initially in the native readv/writev code [1], but was not fixed in the compat code. Thanks to Al for spotting this one.

sbi->s_group_desc is an array of pointers to buffer_head. memcpy() of buffer size from address of buffer_head is a bad idea - it will generate junk in any case, may oops if buffer_head is close to the end of slab page and next page is not mapped and isn't what was intended there. IOW, ->b_data is missing in that call. Fortunately, result doesn't go into the primary on-disk data structures, so only backup ones get crap written to them; that had allowed this bug to remain unnoticed until now.

sys_splice() moves data to/from pipes with a file input/output. sys_vmsplice() moves data to a pipe, with the input being a user address range instead. This uses an approach suggested by Linus, where we can hold partial ranges inside the pages[] map. Hopefully this will be useful for network receive support as well.

BKL does not protect against races if the task may sleep between checking and setting a value. So move checking of file->private_data near to setting it in fuse_fill_super(). Found by Al Viro. Signed-off-by: NMiklos Szeredi <miklos@szeredi.hu>

A deadlock was possible, when the last reference to the superblock was held due to a background request containing a file reference. Releasing the file would release the vfsmount which in turn would release the superblock. Since sbput_sem is held during the fput() and fuse_put_super() tries to acquire this same semaphore, a deadlock results. The solution is to move the fput() outside the region protected by sbput_sem.

This reverts 73ce8355 commit. It was wrong, because it didn't take into account the requirement, that iput() for background requests must be performed synchronously with ->put_super(), otherwise active inodes may remain after unmount. The right solution is to keep the sbput_sem and perform iput() within the locked region, but move fput() outside sbput_sem. Signed-off-by: NMiklos Szeredi <miklos@szeredi.hu>

reiserfs_cache_default_acl() should return whether we successfully found the acl or not. We have to return correct value even if reiserfs_get_acl() returns error code and not just 0. Otherwise callers such as reiserfs_mkdir() can unnecessarily lock the xattrs and later functions such as reiserfs_new_inode() fail to notice that we have already taken the lock and try to take it again with obvious consequences.

This is one of the changes related to journal recovery I mentioned a couple weeks ago. We can get into a situation where there are only readonly nodes currently mounting the fs, but there are journals that need to be recovered. Since the readonly nodes can't recover journals, the next rw mounter needs to go through and check all journals and recover any that are dirty (i.e. what the first node to mount the fs does). This rw mounter needs to skip the journals held by the existing readonly nodes. Skipping those journals amounts to using the TRY flag on the journal locks so acquiring the lock of a journal held by a readonly node will fail instead of blocking indefinately.
