| | | | | | | Convert the journal head integer into the head name when printing debugging information. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBIFS: improve find function interfaceArtem Bityutskiy2009-03-081-3/+2Star
| | | | | | | | Make 'ubifs_find_free_space()' return offset where free space starts, rather than the amount of free space. This is just more appropriat for its caller. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: do not treat all data as short termArtem Bityutskiy2009-01-201-1/+1
| | | | | | | UBIFS wrongly tells UBI that all data is short term. Use proper hints instead. Thanks to Xiaochuan-Xu for noticing this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBIFS: fix writing uncompressed filesArtem Bityutskiy2008-12-311-1/+1
| | | | | | | | | UBIFS does not disable compression if ui->flags is non-zero, e.g. if the file has "sync" flag. This is because of the typo which is fixed by this patch. The patch also adds a couple of useful debugging prints. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: fix checkpatch.pl warningsArtem Bityutskiy2008-12-311-1/+1
| | | | | | | | | | | | | | | | | These are mostly long lines and wrong indentation warning fixes. But also there are two volatile variables and checkpatch.pl complains about them: WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gc_seq; WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gced_lnum; Well, we anyway use smp_wmb() for c->gc_seq and c->gced_lnum, so these 'volatile' modifiers can be just dropped.

* UBIFS: fix compilation warningsArtem Bityutskiy2008-11-061-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We print 'ino_t' type using '%lu' printk() placeholder, but this results in many warnings when compiling for Alpha platform. Fix this by adding (unsingned long) casts.

* UBIFS: xattr bugfixesArtem Bityutskiy2008-08-141-1/+1
| | | | | | | | | | | | | Xattr code has not been tested for a while and there were serveral bugs. One of them is using wrong inode in 'ubifs_jnl_change_xattr()'. The other is a deadlock in 'ubifs_setxattr()': the i_mutex is locked in 'cap_inode_need_killpriv()' path, so deadlock happens when 'ubifs_setxattr()' tries to lock it again. Thanks to Zoltan Sogor for finding these bugs. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: correct orphan deletion orderAdrian Hunter2008-08-131-1/+2
| | | | | | | | | The debug function that checks orphans, does so using the TNC mutex. That means it will not see a correct picture if the inode is removed from the orphan tree before it is removed from TNC. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>

* UBIFS: optimize deletionsArtem Bityutskiy2008-08-131-0/+60
| | | | | | | | | | | Every time anything is deleted, UBIFS writes the deletion inode node twice - once in 'ubifs_jnl_update()' and the second time in 'ubifs_jnl_write_inode()'. However, the second write is not needed if no commit happened after 'ubifs_jnl_update()'. This patch checks that condition and avoids writing the deletion inode for the second time.

* UBIFS: remove another unneeded function parameterArtem Bityutskiy2008-08-131-16/+14Star
| | | | | | | The 'last_reference' parameter of 'pack_inode()' is not really needed because 'inode->i_nlink' may be tested instead. Zap it. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: remove unneeded function parameterArtem Bityutskiy2008-08-131-12/+7Star
| | | | | | | | Simplify 'ubifs_jnl_write_inode()' by removing the 'deletion' parameter which is not really needed because we may test inode->i_nlink and check whether this is a deletion or not. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
