Stop the JFS filesystem from using iget() and read_inode(). Replace jfs_read_inode() with jfs_iget(), and call that instead of iget(). jfs_iget() then uses iget_locked() directly and returns a proper error code instead of an inode in the event of an error. jfs_fill_super() returns any error incurred when getting the root inode instead of EINVAL.

JFS is missing a memory barrier needed to close the critical section before clearing the lock bit. Use lock bitops for this. unlock_page() has a second barrier after clearing the lock, which is required because it checks whether the waitqueue is active without locks. Such a barrier is not required here because the waitqueue spinlock is always taken (something to think about if performance is an issue).

When JFS decides to drop a dirty metapage, it simply clears the META_dirty bit and leave alone the PG_dirty and PAGECACHE_TAG_DIRTY bits. When such no-write page goes to metapage_writepage(), the `relic' PAGECACHE_TAG_DIRTY tag should be cleared, to prevent pdflush from repeatedly trying to sync them. This is done through set_page_writeback(), so call it should be called in all cases. If no I/O is initiated, end_page_writeback() should be called immediately. This is how __block_write_full_page() does things. Signed-off-by: NDave Kleikamp <shaggy@linux.vnet.ibm.com> CC: Fengguang Wu <wfg@mail.ustc.edu.cn>

Introduce is_owner_or_cap() macro in fs.h, and convert over relevant users to it. This is done because we want to avoid bugs in the future where we check for only effective fsuid of the current task against a file's owning uid, without simultaneously checking for CAP_FOWNER as well, thus violating its semantics. [ XFS uses special macros and structures, and in general looked ... untouchable, so we leave it alone -- but it has been looked over. ] The (current->fsuid != inode->i_uid) check in generic_permission() and exec_permission_lite() is left alone, because those operations are covered by CAP_DAC_OVERRIDE and CAP_DAC_READ_SEARCH. Similarly operations falling under the purview of CAP_CHOWN and CAP_LEASE are also left alone.

When the exportfs interface was added the expectation was that filesystems provide an operation to convert from a file handle to an inode/dentry, but it kept a backwards compat option that still calls into iget. Calling into iget from non-filesystem code is very bad, because it gives too little information to filesystem, and simply crashes if the filesystem doesn't implement the ->read_inode routine. Fortunately there are only two filesystems left using this fallback: efs and jfs. This patch moves a copy of export_iget to each of those to implement the get_dentry method. While this is a temporary increase of lines of code in the kernel it allows for a much cleaner interface and important code restructuring in later patches.

I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by SLAB. I think its purpose was to have a callback after an object has been freed to verify that the state is the constructor state again? The callback is performed before each freeing of an object. I would think that it is much easier to check the object state manually before the free. That also places the check near the code object manipulation of the object. Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was compiled with SLAB debugging on. If there would be code in a constructor handling SLAB_DEBUG_INITIAL then it would have to be conditional on SLAB_DEBUG otherwise it would just be dead code. But there is no such code in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real use of, difficult to understand and there are easier ways to accomplish the same effect (i.e. add debug code before kfree). There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be clear in fs inode caches. Remove the pointless checks (they would even be pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors. This is the last slab flag that SLUB did not support. Remove the check for unimplemented flags from SLUB.
