[PATCH] remove dparent_lock

2003-04-03T00:28:58Z

The big SMP machines are seeing quite some contention in dnotify_parent() (via vfs_write). This function is hammering the global dparent_lock. However we don't actually need a global dparent_lock for pinning down dentry->d_parent. We can use dentry->d_lock for this. That is already being held across d_move. This patch speeds up SDET on the 16-way by 5% and wipes dnotify_parent() off the profiles. It also uninlines dnofity_parent(). It also uses spin_lock(), which is faster than read_lock(). I'm not sure that we need to take both the source and target dentry's d_lock in d_move. The patch also does lots of s/__inline__/inline/ in dcache.h

[PATCH] Directory Notification Fix

2002-05-09T05:03:28Z

This patch fixes directory notification so that notifications get cancelled when a process exits. This make dnotify MUCH more stable and usable :-)

[PATCH] dnotify

2002-03-12T04:47:35Z

The following patch makes directory notifications per thread group instead of per process tree as they are now. This means, in particular, that if a child closes a file descriptor that has a directory open with notifies enabled, the notification will not be removed. Thanks to Andrea for the push in the right direction.

[PATCH] ->d_parent fixes

2002-02-25T06:07:54Z

Protect d_parent with "dparent_lock", making ready to get rid of BKL for d_move().

[PATCH] dnotify race fix

2002-02-18T00:35:06Z

A bunch of places dereferences ->d_parent->d_inode with no protection whatsoever (e.g. on return from read()). It's an SMP race on all boxen and pretty wide UP race if we have dnotify set on parent (race between read() and rename() and similar beasts). Patch below is the first one in a series of ->d_parent-related fixes. It adds a helper (dnotify_parent(dentry, event)) and converts places that did inode_dir_notify(dentry->d_parent->d_inode,...) to it. Please, apply. Notice that problem exists in 2.4 and unlike 2.5 there we can't switch to saner API (basically, reporting file events on file, not on a parent directory). Some of the further fixes depend on Pat's and Greg's (driverfs and usbdevfs resp.) patches, so getting them merged would make life easier. And yes, some of further chunks (e.g. smbfs ->revalidate() and friends) will also have to go into 2.4 - they are independent from any threading projects ;-/
