Copy from arch/x86/kernel/irqinit_32.c: we don't use the vectors beyond LGUEST_IRQS (if any), but we might as well set them all. Signed-off-by: NRusty Russell <rusty@rustcorp.com.au>

We hand the /dev/lguest fd everywhere; it's far neater to just make it a global (it already is, in fact, hidden in the waker_fds struct). Signed-off-by: NRusty Russell <rusty@rustcorp.com.au>

We can't trust the values in the device descriptor table once the guest has booted, so keep local copies. They could set them to strange values then cause us to segv (they're 8 bit values, so they can't make our pointers go too wild). This becomes more important with the following patches which read them. Signed-off-by: NRusty Russell <rusty@rustcorp.com.au>

This will remove every bd_mount_sem use in nilfs. The intended exclusion control was replaced by the previous patch ("nilfs2: correct exclusion control in nilfs_remount function") for nilfs_remount(), and this patch will replace remains with a new mutex that this inserts in nilfs object.

nilfs_remount() changes mount state of a superblock instance. Even though nilfs accesses other superblock instances during mount or remount, the mount state was not properly protected in nilfs_remount(). Moreover, nilfs_remount() has a lock order reversal problem; nilfs_get_sb() holds: 1. bdev->bd_mount_sem 2. sb->s_umount (sget acquires) and nilfs_remount() holds: 1. sb->s_umount (locked by the caller in vfs) 2. bdev->bd_mount_sem To avoid these problems, this patch divides a semaphore protecting super block instances from nilfs->ns_sem, and applies it to the mount state protection in nilfs_remount(). With this change, bd_mount_sem use is removed from nilfs_remount() and the lock order reversal will be resolved. And the new rw-semaphore, nilfs->ns_super_sem will properly protect the mount state except the modification from nilfs_error function.

This simplifies the test function passed on the remaining sget() callsite in nilfs. Instead of checking mount type (i.e. ro-mount/rw-mount/snapshot mount) in the test function passed to sget(), this patch first looks up the nilfs_sb_info struct which the given mount type matches, and then acquires the super block instance holding the nilfs_sb_info.

This stops using sget() for checking if an r/w-mount or an r/o-mount exists on the device. This elimination uses a back pointer to the current mount added to nilfs object.

This will change the way to obtain nilfs object in nilfs_get_sb() function. Previously, a preliminary sget() call was performed, and the nilfs object was acquired from a super block instance found by the sget() call. This patch, instead, instroduces a new dedicated function find_or_create_nilfs(); as the name implies, the function finds an existent nilfs object from a global list or creates a new one if no object is found on the device.

The following EBUSY case in nilfs_get_sb() is meaningless. Indeed, this error code is never returned to the caller. if (!s->s_root) { ... } else if (!(s->s_flags & MS_RDONLY)) { err = -EBUSY; } This simply removes the else case.

Now that all filesystems provide ->sync_fs methods we can change __sync_filesystem to only call ->sync_fs. This gives us a clear separation between periodic writeouts which are driven by ->write_super and data integrity syncs that go through ->sync_fs.

* have directory operations use mark_buffer_dirty_inode(), so that sync_mapping_buffers() would get those. * make qnx4_write_inode() honour its last argument. * get rid of insane copies of very ancient "walk the indirect blocks" in qnx4/fsync - they never matched the actual fs layout and, fortunately, never'd been called. Again, all this junk is not needed; ->fsync() should just do sync_mapping_buffers + sync_inode (and if we implement block allocation for qnx4, we'll need to use mark_buffer_dirty_inode() for extent blocks) Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>
