similar to: ext3 and ls in a deletted directory

Hi In ext3_get_parent(), quick string (struct qstr) can do the job, in place of declaring a dentry on stack. Following patch does this and saves few bytes on kernel stack.

This version fixes three bugs in the 2nd patch of this series that caused kernel BUG when the system was under race. We weren't accounting with t_oustanding_credits correctly, and there were race conditions caused by the fact the I had overlooked the fact that __jbd2_log_wait_for_space() and jbd2_get_transaction() requires j_state_lock to be write locked.

jbd2_journal_restart() would restart a handle. In this function, it calls start_this_handle(). Before calling start_this_handle()?subtract 1 from transaction->t_updates. If start_this_handle() succeeds, transaction->t_updates increases by 1 in it. But if start_this_handle() fails, transaction->t_updates does not increase. So, when commit the handle's transaction in

Print the capacity of the block device when the driver is probed. Many users expect this since SCSI disks (sd) do it. Moreover, kernel dmesg output is the primary source of troubleshooting information so it's helpful to include the disk size there. The capacity is already printed by virtio_blk when a resize event occurs. Extract the code and reuse it from virtblk_probe(). This patch also

ocfs2 currently uses the Journaled Block Device (JBD) for its journaling. This is a very stable and tested codebase. However, JBD is limited by architecture to 32bit block numbers. This means an ocfs2 filesystem is limited to 2^32 blocks. With a 4K blocksize, that's 16TB. People want larger volumes. Fortunately, there is now JBD2. JBD2 adds 64bit block number support and some other

LLVM 2.7's ScalarEvolution.cpp has this scary comment: // It's tempting to handle inttoptr and ptrtoint as no-ops, however this can // lead to pointer expressions which cannot safely be expanded to GEPs, // because ScalarEvolution doesn't respect the GEP aliasing rules when // simplifying integer expressions. I think I understand what the comment is saying. If a GEP has

Dear All, As of late I am having a hard time getting my head around how array accesses are translated by Clang into LLVM IR: the often misunderstood GEP instruction. I am trying to reverse-engineer array accesses to discover the number of dimensions and actual indexes of the original, and I am beginning to wonder whether this is possible at all. To illustrate (some of) my troubles, consider
