Function proc_register() will assign proc_dir_operations and proc_dir_inode_operations to ent's members proc_fops and proc_iops correctly if ent is a directory.

Some users have been having problems with utilities like cp or dd dumping core when they try to copy a file that's too large for the destination filesystem (typically, > 4gb). Apparently, some defunct standards required SIGXFSZ to be sent in such circumstances, but SUS only requires/allows it for when a written file exceeds the process's resource limits. I'd like to limit SIGXFSZs to the bare minimum required by SUS.

fs/isofs/* had a bunch of CodingStyle issues. * Indentation was a mix of spaces and tabs * "int * foo" instead of "int *foo" * "while ( foo )" instead of "while (foo)" * if (foo) blah; on one line instead of two * Missing printk KERN_ levels * lots of trailing whitespace * lines >80 columns changed to wrap. * Unnecessary prototype removed by shuffling code order in C file. Should be no functional changes other than slight size increase due to printk changes. Further improvement possible, but this is a start..

invalidate_mapping_pages() can sometimes take a long time (millions of pages to free). Long enough for the softlockup detector to trigger. We used to have a cond_resched() in there but I took it out because the drop_caches code calls invalidate_mapping_pages() under inode_lock.

* 32bit struct xfs_fsop_bulkreq has different size and layout of members, no matter the alignment. Move the code out of the #else branch (why was it there in the first place?). Define _32 variants of the ioctl constants. * 32bit struct xfs_bstat is different because of time_t and on i386 because of different padding. Make xfs_bulkstat_one() accept a custom "output formatter" in the private_data argument which takes care of the xfs_bulkstat_one_compat() that takes care of the different layout in the compat case. * i386 struct xfs_inogrp has different padding.

Avoid using a special "zero inode" as the parent of the quota inode as this can confuse the filestreams code into thinking the quota inode has a parent.

In media spaces, video is often stored in a frame-per-file format. When dealing with uncompressed realtime HD video streams in this format, it is crucial that files do not get fragmented and that multiple files a placed contiguously on disk. When multiple streams are being ingested and played out at the same time, it is critical that the filesystem does not cross the streams and interleave them together as this creates seek and readahead cache miss latency and prevents both ingest and playout from meeting frame rate targets. This patch set creates a "stream of files" concept into the allocator to place all the data from a single stream contiguously on disk so that RAID array readahead can be used effectively. Each additional stream gets placed in different allocation groups within the filesystem, thereby ensuring that we don't cross any streams. When an AG fills up, we select a new AG for the stream that is not in use. The core of the functionality is the stream tracking - each inode that we create in a directory needs to be associated with the directories' stream. Hence every time we create a file, we look up the directories' stream object and associate the new file with that object. Once we have a stream object for a file, we use the AG that the stream object point to for allocations. If we can't allocate in that AG (e.g. it is full) we move the entire stream to another AG. Other inodes in the same stream are moved to the new AG on their next allocation (i.e. lazy update). Stream objects are kept in a cache and hold a reference on the inode. Hence the inode cannot be reclaimed while there is an outstanding stream reference. This means that on unlink we need to remove the stream association and we also need to flush all the associations on certain events that want to reclaim all unreferenced inodes (e.g. filesystem freeze).

A check for file_count is always a bad idea. Linux has the ->release method to deal with cleanups on last close and ->flush is only for the very rare case where we want to perform an operation on every drop of a reference to a file struct. This patch gets rid of vop_close and surrounding code in favour of simply doing the page flushing from ->release.
