| * | UBI: Kill data type hintRichard Weinberger2012-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We do not need this feature and to our shame it even was not working and there was a bug found very recently. -- Artem Bityutskiy Without the data type hint UBI2 (fastmap) will be easier to implement.

| * | UBIFS: fix memory leak on error pathSidney Amani2012-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UBIFS leaks memory on error path in 'mount_ubifs()'. In case of failure in 'ubifs_fixup_free_space()', it does not call 'ubifs_lpt_free()' whereas LPT data structures can potentially be allocated. The amount of memory leaked can be quite high -- see 'ubifs_lpt_init()'. The bug was introduced when moving the LPT initialisation earlier in the mount process (commit '781c5717a95a74b294beb38b8276943b0f8b5bb4').

| * | UBIFS: make ubifs_lpt_init clean-up in case of failureArtem Bityutskiy2012-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most functions in UBIFS follow the following designn pattern: if the function allocates multiple resources, and failss at some point, it frees what it has allocated and returns an error. So the caller can rely on the fact that the callee has cleaned up everything after own failure.

| * | UBIFS: get rid of dbg_errArtem Bityutskiy2012-05-16
| | | | | | | | | | | | | | | | | | | | | | | | This patch removes the 'dbg_err()' macro and we now use 'ubifs_err()' instead. The idea of 'dbg_err()' was to compile out some error message to make the binary a bit smaller - but I think it was a bad idea. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | This commit re-names all functions which dump something from "dbg_dump_*()" to "ubifs_dump_*()".

* / vfs: make it possible to access the dentry hash/len as one 64-bit entryLinus Torvalds2012-05-10
|/ | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the 'i_nlink' counter handling in 'ubifs_unlink()', 'ubifs_rmdir()' and 'ubifs_rename()'. In these function 'i_nlink' may become 0, and if 'ubifs_jnl_update()' failed, we would use 'inc_nlink()' to restore the previous 'i_nlink' value, which is incorrect from the VFS point of view and would cause a 'WARN_ON()' (see 'inc_nlink() implementation). This patches saves the previous 'i_nlink' value in a local variable and uses it at the error path instead of calling 'inc_nlink()'. We do this only for the inodes where 'i_nlink' may potentially become zero. This change has been requested by Al Viro <viro@ZenIV.linux.org.uk>.

| * UBIFS: increase dumps loglevelArtem Bityutskiy2012-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the time we use the dumping function to dump something in case of error. We use 'KERN_DEBUG' printk level, and the drawback is that users do not see them in the console, while they see the other error messages in the console. The result is that they send bug reports which does not contain a lot of useful information. This patch changes the printk level of the dump functions to 'KERN_ERR' to correct the situation. I documented it in the MTD web site that people have to send the 'dmesg' output when submitting bug reposts - it did not help. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | Before commit 56e46742e846e4de167dde0e1e1071ace1c882a5 we have had locking around all printing macros and we could use static buffers for creating key strings and printing them. However, now we do not have that locking and we cannot use static buffers. This commit removes the old DBGKEY() macros and introduces few new helper macros for printing debugging messages plus a key at the end.

However, that patch turned 'dbg_msg()' into 'pr_debug()', so to enable the debugging messages users have to enable them first via /sys/kernel/debug/dynamic_debug/control, which is very impractical. This commit makes 'dbg_msg()' to use 'printk()' instead of 'pr_debug()', just as it was before the breakage.

| * UBIFS: make debugging messages light againArtem Bityutskiy2012-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We switch to dynamic debugging in commit 56e46742e846e4de167dde0e1e1071ace1c882a5 but did not take into account that now we do not control anymore whether a specific message is enabled or not. So now we lock the "dbg_lock" and release it in every debugging macro, which make them not so light-weight. This commit removes the "dbg_lock" protection from the debugging macros to fix the issue. The downside is that now our DBGKEY() stuff is broken, but this is not critical at all and will be fixed later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.
