ubifs: fix to check error code of register_shrinker

2015-06-02T09:41:38+00:00

register_shrinker() in ubifs_init() can fail due to fail to call kzalloc. This patch fixes to check the return value of register_shrinker, otherwise our shrinker may be unregistered after ubifs initialized successfully.

UBIFS: fix output format of INUM_WATERMARK

2015-04-13T10:37:31+00:00

The INUM_WATERMARK is a unsigned 32bit value, `%d' prints it as negatave: [ 103.682255] UBIFS warning (ubi0:0 pid 691): ubifs_new_inode: running out of inode numbers (current 122763, max -256) Fix it as: [ 154.422940] UBIFS warning (ubi0:0 pid 688): ubifs_new_inode: running out of inode numbers (current 122765, max 4294967040) Signed-off-by: Sheng Yong Signed-off-by: Artem Bityutskiy

make new_sync_{read,write}() static

2015-04-12T02:29:40+00:00

All places outside of core VFS that checked ->read and ->write for being NULL or called the methods directly are gone now, so NULL {read,write} with non-NULL {read,write}_iter will do the right thing in all cases. Signed-off-by: Al Viro

fs: move struct kiocb to fs.h

2015-03-26T00:28:11+00:00

struct kiocb now is a generic I/O container, so move it to fs.h. Also do a #include diet for aio.h while we're at it. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

UBIFS: extend debug/message capabilities

2015-03-25T09:08:41+00:00

In the case where we have more than one volumes on different UBI devices, it may be not that easy to tell which volume prints the messages. Add ubi number and volume id in ubifs_msg/warn/error to help debug. These two values are passed by struct ubifs_info. For those where ubifs_info is not initialized yet, ubifs_* is replaced by pr_*. For those where ubifs_info is not avaliable, ubifs_info is passed to the calling function as a const parameter. The output looks like, [ 95.444879] UBIFS (ubi0:1): background thread "ubifs_bgt0_1" started, PID 696 [ 95.484688] UBIFS (ubi0:1): UBIFS: mounted UBI device 0, volume 1, name "test1" [ 95.484694] UBIFS (ubi0:1): LEB size: 126976 bytes (124 KiB), min./max.
