| * Btrfs: fix ioctl arg size (userland incompatible change!)Chris Mason2009-01-162-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The structure used to send device in btrfs ioctl calls was not properly aligned, and so 32 bit ioctls would not work properly on 64 bit kernels. We could fix this with compat ioctls, but we're just one byte away and it doesn't make sense at this stage to carry about the compat ioctls forever at this stage in the project. This patch brings the ioctl arg up to an evenly aligned 4k. Signed-off-by: Chris Mason <chris.mason@oracle.com>
| * Btrfs: Clear the device->running_pending flag before bailing on congestionChris Mason2009-01-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Btrfs maintains a queue of async bio submissions so the checksumming threads don't have to wait on get_request_wait. In order to avoid extra wakeups, this code has a running_pending flag that is used to tell new submissions they don't need to wake the thread. When the threads notice congestion on a single device, they may decide to requeue the job and move on to other devices. This makes sure the running_pending flag is cleared before the job is requeued. It should help avoid IO stalls by making sure the task is woken up when new submissions come in. Signed-off-by: Chris Mason <chris.mason@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | System calls with an unsigned long long argument can't be converted with the standard wrappers since that would include a cast to long, which in turn means that we would lose the upper 32 bit on 32 bit architectures. Also semctl can't use the standard wrapper since it has a 'union' parameter. So we handle them as special case and add some extra wrappers instead.

This did not happen with earlier kernels. The code in sys_pselect7 looks a bit strange, in particular the variable "to" is initialized to NULL, then changed if a non-null timeout was passed in, but not used further. It needs to be passed to core_sys_select instead of &end_time. This bug was introduced by 8ff3e8e85fa6c312051134b3953e397feb639f51 ("select: switch select() and poll() over to hrtimers").

So, we cannot take a backup which keeps the filesystem's consistency with the storage device's features (snapshot and replication) while it is mounted. In many case, a commercial filesystem (e.g. VxFS) has the freeze feature and it would be used to get the consistent backup. If Linux's standard filesystem ext3 has the freeze feature, we can do it without a commercial filesystem. So I have implemented the ioctls of the freeze feature. I think we can take the consistent backup with the following steps. 1. Freeze the filesystem with the freeze ioctl. 2. Separate the replication volume or create the snapshot with the storage device's feature. 3. Unfreeze the filesystem with the unfreeze ioctl. 4. Take the backup from the separated replication volume or the snapshot. This patch: VFS: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that they can return an error. Rename write_super_lockfs and unlockfs of the super block operation freeze_fs and unfreeze_fs to avoid a confusion. ext3, ext4, xfs, gfs2, jfs: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that write_super_lockfs returns an error if needed, and unlockfs always returns 0. reiserfs: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that they always return 0 (success) to keep a current behavior.
