search for: buffer_locked

Hi. I got following BUG trace. This is violation of BUG_ON(!buffer_locked(bh)) check on submit_bh() function. In write_dev_supers(), if wait parameter is set and buffer_uptodate() check is negative, submit_bh() is executed and hit above BUG_ON. So I fixed this issue. Thanks.

restructure try_release_extent_buffer() and write a function to release the extent buffer. It will be used later.

From: Wade Cline <clinew@linux.vnet.ibm.com> This patch is only an RFC. My internship is ending and I was hoping to get some feedback and incorporate any suggestions people may have before my internship ends along with life as we know it (this Friday). The filesystem should mount/umount properly but tends towards the explosive side when writes start happening. My current focus is on

The following series of patches attempts to detach metadata I/O from struct inode. They are currently tied together pretty tightly. Metadata reads happen via the ocfs2_read_blocks() functions, writes via both jbd2 and ocfs2_write_blocks(). - Each inode has a cache of associated metadata blocks stored on its ip_metadata_cache member. The ocfs2_read/write_blocks() functions take a struct
