* zero i_uid/i_gid on inode allocationAl Viro2009-01-0518-43/+2
| | | | | | | | | ... and don't bother in callers. Don't bother with zeroing i_blocks, while we are at it - it's already been zeroed. i_mode is not worth the effort; it has no common default value. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* inode->i_op is never NULLAl Viro2009-01-057-29/+22
| | | | | | | | | | We used to have rather schizophrenic set of checks for NULL ->i_op even though it had been eliminated years ago. You'd need to go out of your way to set it to NULL explicitly _and_ a bunch of code would die on such inodes anyway. After killing two remaining places that still did that bogosity, all that crap can go away. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* vfs: lseek(fd, 0, SEEK_CUR) race conditionAlain Knaff2009-01-051-0/+13
| | | | | | | | | | | | | | | | | | This patch fixes a race condition in lseek. While it is expected that unpredictable behaviour may result while repositioning the offset of a file descriptor concurrently with reading/writing to the same file descriptor, this should not happen when merely *reading* the file descriptor's offset. Unfortunately, the only portable way in Unix to read a file descriptor's offset is lseek(fd, 0, SEEK_CUR); however executing this concurrently with read/write may mess up the position.

Currently, it commits only if there is more than LEB size bytes in the journal. This is not very good, because journal size may be large (512KiB). And there may be few deletions in the journal which do not take much journal space, but which do introduce a lot of TNC changes and make mount slow. Thus, jurt remove this condition and always commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

If the fops->owner field is set, the module reference count of owner is decreases on release. ("filp_close" --> "__fput" ---> "fops_put") On the other hand, anon_inode_getfd does not increase the module reference count of owner. This causes two problems: - if owner is set, the module refcount goes negative - if owner is not set, the module can be unloaded while code is running This patch changes anon_inode_getfd to be symmetric regarding fops->owner handling. I have checked all existing users of anon_inode_getfd. Noone sets fops->owner, thats why nobody has seen the module refcount negative. The refcounting was tested with a patched and unpatched KVM module.(see patch 2/2) I also did an epoll_open/close test.
