ext4: add more tracepoints and use dev_t in the trace buffer

2011-03-22T01:38:05Z

- Add more ext4 tracepoints. - Change ext4 tracepoints to use dev_t field with MAJOR/MINOR macros so that we can save 4 bytes in the ring buffer on some platforms. - Add sync_mode to ext4_da_writepages, ext4_da_write_pages, and ext4_da_writepages_result tracepoints. Also remove for_reclaim field from ext4_da_writepages since it is usually not very useful. Signed-off-by: Jiaying Zhang Signed-off-by: "Theodore Ts'o"

ext4: Initialize fsync transaction ids in ext4_new_inode()

2011-03-16T21:16:31Z

When allocating a new inode, we need to make sure i_sync_tid and i_datasync_tid are initialized. Otherwise, one or both of these two values could be left initialized to zero, which could potentially result in BUG_ON in jbd2_journal_commit_transaction. (This could happen by having journal->commit_request getting set to zero, which could wake up the kjournald process even though there is no running transaction, which then causes a BUG_ON via the J_ASSERT(j_ruinning_transaction != NULL) statement.

ext4: Fix sparse warning: Using plain integer as NULL pointer

2011-02-22T02:01:42Z

This patch fixes the warning "Using plain integer as NULL pointer", generated by sparse, by replacing the offending 0s with NULL. Signed-off-by: Peter Huewe Signed-off-by: "Theodore Ts'o"

fs/vfs/security: pass last path component to LSM on inode creation

2011-02-01T16:12:29Z

SELinux would like to implement a new labeling behavior of newly created inodes. We currently label new inodes based on the parent and the creating process. This new behavior would also take into account the name of the new object when deciding the new label. This is not the (supposed) full path, just the last component of the path. This is very useful because creating /etc/shadow is different than creating /etc/passwd but the kernel hooks are unable to differentiate these operations. We currently require that userspace realize it is doing some difficult operation like that and than userspace jumps through SELinux hoops to get things set up correctly. This patch does not implement new behavior, that is obviously contained in a seperate SELinux patch, but it does pass the needed name down to the correct LSM hook. If no such name exists it is fine to pass NULL. Signed-off-by: Eric Paris

ext4: drop i_state_flags on architectures with 64-bit longs

2011-01-10T17:18:25Z

We can store the dynamic inode state flags in the high bits of EXT4_I(inode)->i_flags, and eliminate i_state_flags. This saves 8 bytes from the size of ext4_inode_info structure, which when multiplied by the number of the number of in the inode cache, can save a lot of memory. Signed-off-by: "Theodore Ts'o"

ext4: make various ext4 functions be static

2010-10-28T01:30:14Z

These functions have no need to be exported beyond file context. No functions needed to be moved for this commit; just some function declarations changed to be static and removed from header files. (A similar patch was submitted by Eric Sandeen, but I wanted to handle code movement in separate patches to make sure code changes didn't accidentally get dropped.)
