2010-08-09mbcache: fix shrinker function return valueAndreas Gruenbacher1-17/+10
The shrinker function is supposed to return the number of cache entries after shrinking, not before shrinking. Fix that. Based on a patch from Wang Sheng-Hui <crosslonelyover@gmail.com>. Signed-off-by: Andreas Gruenbacher <agruen@suse.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-08-09mbcache: Remove unused featuresAndreas Gruenbacher4-122/+55
The mbcache code was written to support a variable number of indexes, but all the existing users use exactly one index. Simplify to code to support only that case. There are also no users of the cache entry free operation, and none of the users keep extra data in cache entries. Remove those features as well.

2010-08-09add f_flags to struct statfs(64)Christoph Hellwig1-1/+46
Add a flags field to help glibc implementing statvfs(3) efficiently. We copy the flag values from glibc, and add a new ST_VALID flag to denote that f_flags is implemented. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-08-09pass a struct path to vfs_statfsChristoph Hellwig7-35/+55
We'll need the path to implement the flags field for statvfs support. We do have it available in all callers except: - ecryptfs_statfs. This one doesn't actually need vfs_statfs but just needs to do a caller to the lower filesystem statfs method. - sys_ustat. Add a non-exported statfs_by_dentry helper for it which doesn't won't be able to fill out the flags field later on. In addition rename the helpers for statfs vs fstatfs to do_*statfs instead of the misleading vfs prefix. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-08-09convert btrfs to ->evict_inode()Al Viro3-4/+8
NB: do we want btrfs_wait_ordered_range() on eviction of inodes with positive i_nlink on subvolume with zero root_refs? If not, btrfs_evict_inode() can be simplified by unconditionally bailing out in case of i_nlink > 0 in the very beginning... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-08-09try to get rid of races in hostfs open()Al Viro3-12/+37
In case of mode mismatch, do *not* blindly close the descriptor another openers might be using right now. Open the underlying file with currently sufficient mode, then * if current mode has grown so that it's sufficient for us now, just close our new fd * if current mode has grown and our fd is *not* enough to cover it, close and repeat. * otherwise, install our fd if the file hadn't been opened at all or dup2() our fd over the current one (and close our fd). Critical section is protected by mutex; yes, system-wide. All we do under it is a bunch of comparison and maybe an overwriting dup2() on host. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-08-09hostfs: fix races in dentry_name() and inode_name()Al Viro1-46/+60
calculating size, then doing allocation, then filling the path is a Bad Idea(tm), since the ancestors can be renamed, leading to buffer overrun. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-08-09hostfs: pass pathname to init_inode()Al Viro1-30/+15
We will calculate it in all callers anyway, so there's no need to duplicate that inside. Moreover, that way we lose all failure exits in init_inode(), so it doesn't need to return anything. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

There are only two call sites; in one (hostfs_iget()) it's actually a no-op and in another (fill_super()) it's easier to expand the damn thing and use what we know about its arguments to simplify it. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
