[PATCH] fix up new filp allocators

2008-03-19T10:54:05Z

Some new uses of get_empty_filp() have crept in; switched to alloc_file() to make sure that pieces of initialization won't be missing. We really need to kill get_empty_filp().

sched: affine sync wakeups

2007-10-15T15:00:19Z

make sync wakeups affine for cache-cold tasks: if a cache-cold task is woken up by a sync wakeup then use the opportunity to migrate it straight away. (the two tasks are 'related' because they communicate) Signed-off-by: Ingo Molnar

sched: cleanup, remove the TASK_NONINTERACTIVE flag

pipe: add documentation and comments

2007-07-10T06:04:16Z

As per Andrew Mortons request, here's a set of documentation for the generic pipe_buf_operations hooks, the pipe, and pipe_buffer structures. Signed-off-by: Jens Axboe

pipe: change the ->pin() operation to ->confirm()

2007-07-10T06:04:15Z

The name 'pin' was badly chosen, it doesn't pin a pipe buffer in the most commonly used sense in the kernel. So change the name to 'confirm', after debating this issue with Hugh Dickins a bit. A good return from ->confirm() means that the buffer is really there, and that the contents are good. Signed-off-by: Jens Axboe

VFS: delay the dentry name generation on sockets and pipes

2007-05-08T18:15:03Z

1) Introduces a new method in 'struct dentry_operations'. This method called d_dname() might be called from d_path() to build a pathname for special filesystems. It is called without locks. Future patches (if we succeed in having one common dentry for all pipes/sockets) may need to change prototype of this method, but we now use : char *d_dname(struct dentry *dentry, char *buffer, int buflen); 2) Adds a dynamic_dname() helper function that eases d_dname() implementations 3) Defines d_dname method for sockets : No more sprintf() at socket creation. This is delayed up to the moment someone does an access to /proc/pid/fd/... 4) Defines d_dname method for pipes : No more sprintf() at pipe creation. This is delayed up to the moment someone does an access to /proc/pid/fd/...
