Hello, while fixing some problems with preallocation in UDF, I had a look how ext2 solves similar problems. I found out that ext2_discard_prealloc() is called on every iput() from ext2_put_inode(). Is it really appropriate? I don't see a reason for doing so... Also I found slightly misleading the comment at ext2_release_file(). As far as I understand the code it isn't when /all/ files are closed but rather when all fd's for given filp are closed. I.e. if you open the same file two times, ->release will get called once for each open. Am I right? If so, then also calling ext2_discard_prealloc() from ext2_release_file() is suboptimal, isn't it?
