sysfs: add proper sysfs_init() prototype

2006-09-26T04:08:39+00:00

Don't be crufty. Mark it __must_check too. Cc: "Randy.Dunlap" Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman

add __must_check to device management code

2006-09-26T04:08:39+00:00

We're getting a lot of crashes in the sysfs/kobject/device/bus/class code and they're very hard to diagnose. I'm suspecting that in some cases this is because drivers aren't checking return values and aren't handling errors correctly. So the code blithely blunders on and crashes later in very obscure ways. There's just no reason to ignore errors which can and do occur. So the patch sprinkles __must_check all over these APIs. Causes 1,513 new warnings. Heh.

sysfs_remove_bin_file: no return value, dump_stack on error

2006-09-26T04:08:39+00:00

Make sysfs_remove_bin_file() void. If it detects an error, printk the file name and call dump_stack(). sysfs_hash_and_remove() now returns an error code indicating its success or failure so that sysfs_remove_bin_file() can know success/failure. Convert the only driver that checked the return value of sysfs_remove_bin_file(). Signed-off-by: Randy Dunlap Signed-off-by: Greg Kroah-Hartman

[PATCH] sysfs: Allow sysfs attribute files to be pollable

2006-04-14T18:41:24+00:00

It works like this: Open the file Read all the contents. Call poll requesting POLLERR or POLLPRI (so select/exceptfds works) When poll returns, close the file and go to top of loop. or lseek to start of file and go back to the 'read'. Events are signaled by an object manager calling sysfs_notify(kobj, dir, attr); If the dir is non-NULL, it is used to find a subdirectory which contains the attribute (presumably created by sysfs_create_group). This has a cost of one int per attribute, one wait_queuehead per kobject, one int per open file. The name "sysfs_notify" may be confused with the inotify functionality. Maybe it would be nice to support inotify for sysfs attributes as well? This patch also uses sysfs_notify to allow /sys/block/md*/md/sync_action to be pollable Signed-off-by: Neil Brown Signed-off-by: Greg Kroah-Hartman

[PATCH] sysfs-iattr: add sysfs_setattr

2005-06-20T22:15:37+00:00

o This adds ->i_op->setattr VFS method for sysfs inodes. The changed attribues are saved in the persistent sysfs_dirent structure as a pointer to struct iattr. The struct iattr is allocated only for those sysfs_dirent's for which default attributes are getting changed. Thanks to Jon Smirl for this suggestion.

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
