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.

UBIFS: remove useless statements

UBIFS: Add an assertion for clean_zn_cnt

2014-06-03T08:16:51+00:00

This patch adds a new ubifs_assert() in ubifs_tnc_close() to check if there are any leaks of per-filesystem @clean_zn_cnt. This new assert inspects whether the return value of ubifs_destroy_tnc_subtree() is equal to @clean_zn_cnt or not while umount.

fs/ubifs: use rbtree postorder iteration helper instead of opencoding

UBIFS: remove Kconfig debugging option

2012-05-16T16:53:46+00:00

Have the debugging stuff always compiled-in instead. It simplifies maintanance a lot. Signed-off-by: Artem Bityutskiy

UBIFS: rename dumping functions

2012-05-16T16:15:56+00:00

This commit re-names all functions which dump something from "dbg_dump_*()" to "ubifs_dump_*()". This is done for consistency with UBI and because this way it will be more logical once we remove the debugging sompilation option. Signed-off-by: Artem Bityutskiy

UBIFS: get rid of dbg_dump_stack

2012-05-16T16:04:54+00:00

In case of errors we almost always need the stack dump - it makes no sense to compile it out. Remove the 'dbg_dump_stack()' function completely. Signed-off-by: Artem Bityutskiy

vfs: make it possible to access the dentry hash/len as one 64-bit entry

2012-05-11T02:54:35+00:00

This allows comparing hash and len in one operation on 64-bit architectures. Right now only __d_lookup_rcu() takes advantage of this, since that is the case we care most about. The use of anonymous struct/unions hides the alternate 64-bit approach from most users, the exception being a few cases where we initialize a 'struct qstr' with a static initializer. This makes the problematic cases use a new QSTR_INIT() helper function for that (but initializing just the name pointer with a "{ .name = xyzzy }" initializer remains valid, as does just copying another qstr structure).
