Subject: [patch 0/6] fix i_mutex locking in splice to file

Jens, Mark,

This series deals with the problem of generic_file_splice_write() and
ocfs2_file_splice_write() holding i_mutex (and ocfs2 lock) on
destination inode across pipe_wait(), which waits for a user
controlled event.

Lightly tested on ext3. The OCFS2 changes have only been compile
tested.

Please review/test.

Thanks,
Miklos

Thanks Miklos, I've integrated it for testing. Looks good!
