2012-03-18	38a1971 Browse files » FAT: Fix error path ... - forward the return value of chk_mounted to detect whether mount succeeded - free resources on mount failure Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 18 Mar 2012
	3f637f7 Browse files » fs open: pass error from stat ... We used to simply answer with -ENOENT in open() when the initial call to stat() failed. Instead, forward the error from stat(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 18 Mar 2012
	b5e5b06 Browse files » Add automount support ... This patch adds an automount command which makes it possible to execute a script when a certain directory is first accessed. It's the commands responsibility to make this directory available (bringing devices up and mounting it). This results in automount support which makes sure that from the shell every file can be accessed without having to care for device bringup. Bringing up devices may be expensive (USB, dhcp). The automount support makes it easy for the environment to bringup devices when they are actually needed. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 18 Mar 2012
2012-03-17	b55fbf7 Browse files » fs: drop struct mtab_entry ... every struct fs_device_d contains a struct mtab_entry, so they have a 1:1 relationship. Instead of having to use container_of to get from a struct mtab_entry to a struct fs_device_d we can better embed the members of struct mtab_entry into struct fs_device_d directly.

2012-03-17	4b4bfcc Browse files » fs: change get_fs_device_by_path prototype ... get_fs_device_by_path returns a struct device_d instead of what the name suggests a struct fs_device_d. Also it returns the rootpath of the corresponding fs_device. This patch changes the name of this function to get_fs_device_and_root_path to better reflect what the function does and changes the return type to struct fs_device_d.

2012-02-19	abd21d1 Browse files » Add suport for tftp as a filesystem ... This adds tftp filesystem support. It currently duplicates significant amounts of the tftp (command) support. This is ok since we can eventually drop the original tftp command later. tftp is not really suitable to be handled as a filesystem. It lacks support for stat, reading directories and other things. Handling it as a filesystem has one big advantage though: tftp is no special case for boot scripts and/or commands anymore which makes them simpler. This implementation has some improvements to the original tftp command. It supports blocksize negotiation which speeds up transfers if the tftp server supports it. Also we can determine the filesize to transfer if the remote end supports it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 19 Feb 2012

	62d8b2f Browse files » fs: allow to mount on subdirectories ... Since get_mtab_entry_by_path() is a bit more flexible now we no longer have to force the user to mount on the root directory only. Instead, we can allow to mount on subdirectories aswell. Nested mounts are still not possible though. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 17 Feb 2012
	9bf08d5 Browse files » fs: put fs devices on its own bus ... By putting the fs devices/drivers on a bus on its own we can hook into the bus remove function to cleanup the fs device. This way we can unmount a device by simply unregistering the device which is useful for for example USB mass storage devices. These can now unregister the assoiated filesystems by unregistering their child devices. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 17 Feb 2012
	33b5ead Browse files » fs: remove fs devices list ... We store the fs devices in a list only because we want to check if the fs driver needs a backingstore or not. The driver will bail out anyway if it needs a backingstore and doesn't find one. So we can remove this check and thus remove the list of fs devices.

The problem is the mount function in fs/fs.c. parent_device is initialized to NULL and never updated. With this patch, parent_device is set with the mounted device name. Moreover, the mount function has been modified to print the device name plus device id using the dev_name function.
