* sysfs: move sysfs file poll implementation to sysfs_open_direntTejun Heo2007-10-125-10/+19
| | | | | | | | | | | | | | | | | | | | | | | | | Sysfs file poll implementation is scattered over sysfs and kobject. Event numbering is done in sysfs_dirent but wait itself is done on kobject. This not only unecessarily bloats both kobject and sysfs_dirent but is also buggy - if a sysfs_dirent is removed while there still are pollers, the associaton betwen the kobject and sysfs_dirent breaks and kobject may be freed with the pollers still sleeping on it. This patch moves whole poll implementation into sysfs_open_dirent. Each time a sysfs_open_dirent is created, event number restarts from 1 and pollers sleep on sysfs_open_dirent. As event sequence number is meaningless without any open file and pollers should have open file and thus sysfs_open_dirent, this ephemeral event counting works and is a saner implementation. This patch fixes the dnagling sleepers bug and reduces the sizes of kobject and sysfs_dirent by one pointer.

* sysfs: implement sysfs_open_direntTejun Heo2007-10-122-1/+111
| | | | | | | | | | | | | | | Implement sysfs_open_dirent which represents an open file (attribute) sysfs_dirent. A file sysfs_dirent with one or more open files have one sysfs_dirent and all sysfs_buffers (one for each open instance) are linked to it. sysfs_open_dirent doesn't actually do anything yet but will be used to off-load things which are specific for open file sysfs_dirent from it.

* sysfs: Introduce sysfs_rename_mutexEric W. Biederman2007-10-123-1/+12
| | | | | | | | | | | | | | | | | | | | | Looking carefully at the rename code we have a subtle dependency that the structure of sysfs not change while we are performing a rename. If the parent directory of the object we are renaming changes while the rename is being performed nasty things could happen when we go to release our locks. So introduce a sysfs_rename_mutex to prevent this highly unlikely theoretical issue. In addition hold sysfs_rename_mutex over all calls to sysfs_get_dentry.

* sysfs: Rewrite sysfs_drop_dentry.Eric W. Biederman2007-10-121-27/+26
| | | | | | | | | | | | | Currently we find the dentry to drop by looking at sd->s_dentry. We can just as easily accomplish the same task by looking up the sysfs inode and finding all of the dentries from there, with the added bonus that we don't need to play with the sysfs_assoc_lock.

* sysfs: Simplify readdir.Eric W. Biederman2007-10-121-131/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | At some point someone wrote sysfs_readdir to insert a cursor into the list of sysfs_dirents to ensure that sysfs_readdir would restart properly. That works but it is complex code and tends to be expensive. The same effect can be achieved by keeping the sysfs_dirents in inode order and using the inode number as the f_pos. Then when we restart we just have to find the first dirent whose inode number is equal or greater then the last sysfs_dirent we attempted to return. Removing the sysfs directory cursor also allows the remove of all of the mysterious checks for sysfs_type(sd) != 0. Which were nonbovious checks to see if a cursor was in a directory list. tj: offset marker for EOF is changed from UINT_MAX to INT_MAX to avoid overflow in case offset is 32bit.
