* ocfs2: Clear undo bits when local alloc is freedMark Fasheh2010-03-23
| | | | | | | | | | | | | | When the local alloc file changes windows, unused bits are freed back to the global bitmap. By defnition, those bits can not be in use by any file. Also, the local alloc will never have been able to allocate those bits if they were part of a previous truncate. Therefore it makes sense that we should clear unused local alloc bits in the undo buffer so that they can be used immediatly.

* ocfs2: Fix the update of name_offset when removing xattrsTao Ma2010-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When replacing a xattr's value, in some case we wipe its name/value first and then re-add it. The wipe is done by ocfs2_xa_block_wipe_namevalue() when the xattr is in the inode or block. We currently adjust name_offset for all the entries which have (offset < name_offset). This does not adjust the entrie we're replacing. Since we are replacing the entry, we don't adjust the total entry count. When we calculate a new namevalue location, we trust the entries now-wrong offset in ocfs2_xa_get_free_start(). The solution is to also adjust the name_offset for the replaced entry, allowing ocfs2_xa_get_free_start() to calculate the new namevalue location correctly. The following script can trigger a kernel panic easily. echo 'y'|mkfs.ocfs2 --fs-features=local,xattr -b 4K $DEVICE mount -t ocfs2 $DEVICE $MNT_DIR FILE=$MNT_DIR/$RANDOM for((i=0;i<76;i++)) do string_76="a$string_76" done string_78="aa$string_76" string_82="aaaa$string_78" touch $FILE setfattr -n 'user.test1234567890' -v $string_76 $FILE setfattr -n 'user.test1234567890' -v $string_78 $FILE setfattr -n 'user.test1234567890' -v $string_82 $FILE Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: Always try for maximum bits with new local alloc windowsMark Fasheh2010-03-18
| | | | | | | | | | | | | | | What we were doing before was to ask for the current window size as the maximum allocation. This had the effect of limiting the amount of allocation we could get for the local alloc during times when the window size was shrunk due to fragmentation. In some cases, that could actually *increase* fragmentation by artificially limiting the number of bits we can accept. So while we still want to ask for a minimum number of bits equal to window size, there is no reason why we should limit the number of bits the local alloc should accept. Hence always allow the maximum number of local alloc bits. Signed-off-by: Mark Fasheh <mfasheh@suse.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: set i_mode on disk during acl operationsMark Fasheh2010-03-17
| | | | | | | | | | | | ocfs2_set_acl() and ocfs2_init_acl() were setting i_mode on the in-memory inode, but never setting it on the disk copy. Thus, acls were some times not getting propagated between nodes. This patch fixes the issue by adding a helper function ocfs2_acl_set_mode() which does this the right way. ocfs2_set_acl() and ocfs2_init_acl() are then updated to call ocfs2_acl_set_mode().

* ocfs2: Change bg_chain check for ocfs2_validate_gd_parent.Tao Ma2010-03-17
| | | | | | | | | | | | | | | | | In ocfs2_validate_gd_parent, we check bg_chain against the cl_next_free_rec of the dinode. Actually in resize, we have the chance of bg_chain == cl_next_free_rec. So add some additional condition check for it. I also rename paramter "clean_error" to "resize", since the old one is not clearly enough to indicate that we should only meet with this case in resize. btw, the correpsonding bug is http://oss.oracle.com/bugzilla/show_bug.cgi?id=1230.

* [PATCH] Skip check for mandatory locks when unlockingSachin Prabhu2010-03-17
| | | | | | | | | | | | ocfs2_lock() will skip locks on file which has mode set to 02666. This is a problem in cases where the mode of the file is changed after a process has obtained a lock on the file. ocfs2_lock() should skip the check for mandatory locks when unlocking a file.

But it has pieces of code that should always be built statically into the kernel. The plan is for processor_core.c to contain the static bits while processor_driver.c contains the module-like bits. Since the bulk of the code in the current processor_core.c is module-like, first step is to rename the file to processor_driver.c Next step will re-create processor_core.c and cherry-pick out the static bits.

There's no benefit in us always requesting the state of the fan when performing transitions - we want to do everything we can to ensure that the fan turns on when it should do, not risk hardware damage by believing the hardware when it tells us the fan is already on. Given that the Leading Other OS(tm) works fine on this machine, it seems likely that it behaves in much this way. inspired-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
