ocfs2: why not set EROFS when clearing bits multiple times
In ocfs2_block_group_clear_bits, when num_bits != bits_cleared, it just
log an error message without setting EROFS.
The code is below:
/*
* If encountered, it means we are clearing bits multiple times. While
* we are handling the case, we still need to be alerted to its
* occurrence. Hence, marking it as an ERROR and not...

[PATCH 0/40] ocfs2: Detach ocfs2 metadata I/O from struct inode
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
