UBI: fix return error code

2015-12-16T21:45:04Z

We are checking dfs_rootdir for error value or NULL. But in the conditional ternary operator we returned -ENODEV if dfs_rootdir contains an error value and returned PTR_ERR(dfs_rootdir) if dfs_rootdir is NULL. So in the case of dfs_rootdir being NULL we actually assigned 0 to err and returned it to the caller implying a success. Lets return -ENODEV when dfs_rootdir is NULL else return PTR_ERR(dfs_rootdir).

UBI: power cut emulation for testing

2015-04-13T19:05:17Z

Emulate random power cuts by switching device to ro after a number of writes to allow simple power cut testing with nand-sim. Maximum and minimum number of successful writes before power cut and what kind of writes (EC header, VID header or none) to interrupt configurable via debugfs.

UBI: Add initial support for fastmap self checks

UBI: Extend UBI layer debug/messaging capabilities

2014-11-07T10:08:51Z

If there is more then one UBI device mounted, there is no way to distinguish between messages from different UBI devices. Add device number to all ubi layer message types. The R/O block driver messages were replaced by pr_* since ubi_device structure is not used by it. Amended a bit by Artem. Signed-off-by: Tanya Brokhman Signed-off-by: Artem Bityutskiy

UBI: embed ubi_debug_info field in ubi_device struct

2012-12-10T11:38:59Z

ubi_debug_info struct was dynamically allocated which is always suboptimal, for it tends to fragment memory and make the code error-prone. Fix this by embedding it in ubi_device struct. Signed-off-by: Ezequiel Garcia Signed-off-by: Artem Bityutskiy

UBI: use pr_ helper instead of printk

Use 'pr_err()' instead of 'printk(KERN_ERR', etc. Signed-off-by: Artem Bityutskiy

UBI: comply with coding style

UBI: correct usage of IS_ENABLED()

2012-06-27T11:22:15Z

Commit "e9b4cf2 UBI: fix debugfs-less systems support" fixed one regression but introduced a different regression - the debugfs is now always compiled out. Root cause: IS_ENABLED() arguments should be used with the CONFIG_* prefix. Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy

UBI: fix debugfs-less systems support

2012-06-07T07:43:54Z

Commit "aa44d1d UBI: remove Kconfig debugging option" broke UBI and it refuses to initialize if debugfs (CONFIG_DEBUG_FS) is disabled. I incorrectly assumed that debugfs files creation function will return success if debugfs is disabled, but they actually return -ENODEV. This patch fixes the issue.

UBI: rename sv to av

2012-05-20T17:26:02Z

After re-naming the 'struct ubi_scan_volume' we should adjust all variables named 'sv' to something else, because 'sv' stands for "scanning volume". Let's rename it to 'av' which stands for "attaching volume" which is a bit more consistent and has the same length, which makes re-naming easy. Signed-off-by: Artem Bityutskiy
