->encode_fh() API change

2012-05-30T03:28:33Z

pass inode + parent's inode or NULL instead of dentry + bool saying whether we want the parent or not. NOTE: that needs ceph fix folded in. Signed-off-by: Al Viro

exportfs: Return the minimum required handle size

2011-03-14T13:15:28Z

The exportfs encode handle function should return the minimum required handle size. This helps user to find out the handle size by passing 0 handle size in the first step and then redoing to the call again with the returned handle size value.

fs: dcache per-inode inode alias locking

2011-01-07T06:50:31Z

dcache_inode_lock can be replaced with per-inode locking. Use existing inode->i_lock for this. This is slightly non-trivial because we sometimes need to find the inode from the dentry, which requires d_inode to be stabilised (either with refcount or d_lock). Signed-off-by: Nick Piggin

fs: dcache rationalise dget variants

2011-01-07T06:50:24Z

dget_locked was a shortcut to avoid the lazy lru manipulation when we already held dcache_lock (lru manipulation was relatively cheap at that point). However, how that the lru lock is an innermost one, we never hold it at any caller, so the lock cost can now be avoided. We already have well working lazy dcache LRU, so it should be fine to defer LRU manipulations to scan time. Signed-off-by: Nick Piggin

fs: dcache remove dcache_lock

2011-01-07T06:50:23Z

dcache_lock no longer protects anything. remove it. Signed-off-by: Nick Piggin

fs: scale inode alias list

2011-01-07T06:50:22Z

Add a new lock, dcache_inode_lock, to protect the inode's i_dentry list from concurrent modification. d_alias is also protected by d_lock. Signed-off-by: Nick Piggin

exportfs: use dget_parent

2010-10-26T01:26:13Z

Use dget_parent instead of opencoding it. This simplifies the code, but more importanly prepares for the more complicated locking for a parent dget in the dcache scale patch series. Signed-off-by: Al Viro
