ocfs2: use 'oi' instead of 'OCFS2_I()'

We could use 'oi' instead of 'OCFS2_I()' to make code more elegant.

ocfs2: replace CURRENT_TIME macro

2016-12-13T02:55:06Z

CURRENT_TIME is not y2038 safe. Use y2038 safe ktime_get_real_seconds() here for timestamps. struct heartbeat_block's hb_seq and deletetion time are already 64 bits wide and accommodate times beyond y2038. Also use y2038 safe ktime_get_real_ts64() for on disk inode timestamps. These are also wide enough to accommodate time64_t.

ocfs2: fix improper handling of return errno

2016-05-26T22:35:44Z

Previously, if a bad inode was found in ocfs2_iget(), -ESTALE was returned back to the caller anyway. Since commit d2b9d71a2da7 ("ocfs2: check/fix inode block for online file check") can handle with return value from ocfs2_read_locked_inode() now, we know the exact errno returned for us.

parallel lookups: actual switch to rwsem

2016-05-02T23:49:28Z

ta-da! The main issue is the lack of down_write_killable(), so the places like readdir.c switched to plain inode_lock(); once killable variants of rwsem primitives appear, that'll be dealt with. lockdep side also might need more work Signed-off-by: Al Viro

ocfs2: record UNWRITTEN extents when populate write desc

2016-03-25T23:37:42Z

To support direct io in ocfs2_write_begin_nolock & ocfs2_write_end_nolock. There is still one issue in the direct write procedure. phase 1: alloc extent with UNWRITTEN flag phase 2: submit direct data to disk, add zero page to page cache phase 3: clear UNWRITTEN flag when data has been written to disk When there are 2 direct write A(0~3KB),B(4~7KB) writing to the same cluster 0~7KB (cluster size 8KB). Write request A arrive phase 2 first, it will zero the region (4~7KB). Before request A enter to phase 3, request B arrive phase 2, it will zero region (0~3KB). This is just like request B steps request A. To resolve this issue, we should let request B knows this cluster is already under zero, to prevent it from steps the previous write request. This patch will add function ocfs2_unwritten_check() to do this job. It will record all clusters that are under direct write(it will be recorded in the 'ip_unwritten_list' member of inode info), and prevent the later direct write writing to the same cluster to do the zero work again.
