2009-06-16btrfs: properly register fs backing deviceJens Axboe
btrfs assigns this bdi to all inodes on that file system, so make sure it's registered. This isn't really important now, but will be when we put dirty inodes there. Even now, we miss the stats when the bdi isn't visible. Also fixes failure to check bdi_init() return value, and bad inherit of ->capabilities flags from the default bdi.

2009-06-14ramfs: ignore unknown mount optionsMike Frysinger
On systems where CONFIG_SHMEM is disabled, mounting tmpfs filesystems can fail when tmpfs options are used. This is because tmpfs creates a small wrapper around ramfs which rejects unknown options, and ramfs itself only supports a tiny subset of what tmpfs supports. This makes it pretty hard to use the same userspace systems across different configuration systems. As such, ramfs should ignore the tmpfs options when tmpfs is merely a wrapper around ramfs. This used to work before commit c3b1b1cbf0 as previously, ramfs would ignore all options. But now, we get: ramfs: bad mount option: size=10M mount: mounting mdev on /dev failed: Invalid argument Another option might be to restore the previous behavior, where ramfs simply ignored all unknown mount options ... which is what Hugh prefers.

2009-06-12GFS2: Add tracepointsSteven Whitehouse
This patch adds the ability to trace various aspects of the GFS2 filesystem. The trace points are divided into three groups, glocks, logging and bmap. These points have been chosen because they allow inspection of the major internal functions of GFS2 and they are also generic enough that they are unlikely to need any major changes as the filesystem evolves.

This will remove every bd_mount_sem use in nilfs.

2009-06-11nilfs2: correct exclusion control in nilfs_remount functionRyusuke Konishi
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.

2009-06-11nilfs2: simplify remaining sget() useRyusuke Konishi
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.

2009-06-11nilfs2: get rid of sget use for acquiring nilfs objectRyusuke Konishi
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.
