* ide: turn selectproc() method into dev_select() method (take 5)Sergei Shtylyov2009-03-311-3/+3
| | | | | | | | | | | Turn selectproc() method into dev_select() method by teaching it to write to the device register and moving it from 'struct ide_port_ops' to 'struct ide_tp_ops'.

* ide: rename IDE_TFLAG_IN_[HOB_]FEATURESergei Shtylyov2009-03-311-4/+8
| | | | | | | | | | The feature register has never been readable -- when its location is read, one gets the error register value; hence rename IDE_TFLAG_IN_[HOB_]FEATURE into IDE_TFLAG_IN_[HOB_]ERROR and introduce the 'hob_error' field into the 'struct ide_taskfile' (despite the error register not really depending on the HOB bit).

| | | | | | | | | | struct ide_atapi_pc is often allocated on the stack and size of ->pc_buf size is 256 bytes. However since only ide_floppy_create_read_capacity_cmd() and idetape_create_inquiry_cmd() require such size allocate buffers for these pc-s explicitely and decrease ->pc_buf size to 64 bytes.

| * reiserfs: add atomic addition of selinux attributes during inode creationJeff Mahoney2009-03-302-1/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | Some time ago, some changes were made to make security inode attributes be atomically written during inode creation. ReiserFS fell behind in this area, but with the reworking of the xattr code, it's now fairly easy to add. The following patch adds the ability for security attributes to be added automatically during inode creation.

| * reiserfs: use generic readdir for operations across all xattrsJeff Mahoney2009-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current reiserfs xattr implementation open codes reiserfs_readdir and frees the path before calling the filldir function. Typically, the filldir function is something that modifies the file system, such as a chown or an inode deletion that also require reading of an inode associated with each direntry. Since the file system is modified, the path retained becomes invalid for the next run. In addition, it runs backwards in attempt to minimize activity. This is clearly suboptimal from a code cleanliness perspective as well as performance-wise. This patch implements a generic reiserfs_for_each_xattr that uses the generic readdir and a specific filldir routine that simply populates an array of dentries and then performs a specific operation on them. When all files have been operated on, it then calls the operation on the directory itself. The result is a noticable code reduction and better performance.

| * reiserfs: journaled xattrsJeff Mahoney2009-03-303-3/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Deadlocks are possible in the xattr code between the journal lock and the xattr sems. This patch implements journalling for xattr operations. The benefit is twofold: * It gets rid of the deadlock possibility by always ensuring that xattr write operations are initiated inside a transaction. * It corrects the problem where xattr backing files aren't considered any differently than normal files, despite the fact they are metadata. I discussed the added journal load with Chris Mason, and we decided that since xattrs (versus other journal activity) is fairly rare, the introduction of larger transactions to support journaled xattrs wouldn't be too big a deal.

| * reiserfs: use generic xattr handlersJeff Mahoney2009-03-303-35/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Christoph Hellwig had asked me quite some time ago to port the reiserfs xattrs to the generic xattr interface. This patch replaces the reiserfs-specific xattr handling code with the generic struct xattr_handler. However, since reiserfs doesn't split the prefix and name when accessing xattrs, it can't leverage generic_{set,get,list,remove}xattr without needlessly reconstructing the name on the back end. Update 7/26/07: Added missing dput() to deletion path. Update 8/30/07: Added missing mark_inode_dirty when i_mode is used to represent an ACL and no previous ACL existed.

| * reiserfs: make per-inode xattr locking more fine grainedJeff Mahoney2009-03-302-23/+1
| | | | | | | | | | | | | | | | | | | | The per-inode locking can be made more fine-grained to surround just the interaction with the filesystem itself. This really only applies to protecting reads during a write, since concurrent writes are barred with inode->i_mutex at the vfs level.

| * reiserfs: eliminate per-super xattr lockJeff Mahoney2009-03-303-29/+5
| | | | | | | | | | | | | | | | | | | | With the switch to using inode->i_mutex locking during lookups/creation in the xattr root, the per-super xattr lock is no longer needed. This patch removes it.

| * reiserfs: Clean up xattrs when REISERFS_FS_XATTR is unsetJeff Mahoney2009-03-302-24/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current reiserfs xattr implementation will not clean up old xattr files if files are deleted when REISERFS_FS_XATTR is unset. This results in inaccessible lost files, wasting space. This patch compiles in basic xattr knowledge, such as how to delete them and change ownership for quota tracking. If the file system has never used xattrs, then the operation is quite fast: it returns immediately when it sees there is no .reiserfs_priv directory.

| * reiserfs: remove IS_PRIVATE helpersJeff Mahoney2009-03-301-8/+0
| | | | | | | | | | | | | | | | | | | | There are a number of helper functions for marking a reiserfs inode private that were leftover from reiserfs did its own thing wrt to private inodes.

| | | | | | | | | | | | | | | | | | | | | | | | Although reiserfs can currently handle severe errors such as journal failure, it cannot handle less severe errors like metadata i/o failure.

| | | | | | | | | | | | | | | | | | | | | | This patch kills off reiserfs_journal_abort as it is never called, and combines __reiserfs_journal_abort_{soft,hard} into one function called reiserfs_abort_journal, which performs the same work.

In some cases: * a unique identifier may be associated with it * the function name may be included * the device may be printed separately This patch aims to make warnings more consistent. reiserfs_warning() prints the device name, so printing it a second time is not required. The function name for a warning is always helpful in debugging, so it is now automatically inserted into the output. Hans has stated that every warning should have a unique identifier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes up the reiserfs code such that transaction ids are always unsigned ints. In places they can currently be signed ints or unsigned longs. The former just causes an annoying clm-2200 warning and may join a transaction when it should wait. The latter is just for correctness since the disk format uses a 32-bit transaction id. There aren't any runtime problems that result from it not wrapping at the correct location since the value is truncated correctly even on big endian systems. The 0 value might make it to disk, but the mount-time checks will bump it to 10 itself. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The problem was originally reported here: http://marc.info/?l=linux-kernel&m=123383810628583&w=2 Change is_linear_pfn_mapping logic to overload VM_INSERTPAGE flag along with VM_PFNMAP to mean full PFNMAP setup at mmap time.
