nilfs2: Fix some kernel-doc comments

2022-05-12T14:49:23Z

The description of @flags in nilfs_dirty_inode() kernel-doc comment is missing, and some functions had kernel-doc that used a hash instead of a colon to separate the parameter name from the one line description. Fix them to remove some warnings found by running scripts/kernel-doc, which is caused by using 'make W=1'. fs/nilfs2/inode.c:73: warning: Function parameter or member 'inode' not described in 'nilfs_get_block' fs/nilfs2/inode.c:73: warning: Function parameter or member 'blkoff' not described in 'nilfs_get_block' fs/nilfs2/inode.c:73: warning: Function parameter or member 'bh_result' not described in 'nilfs_get_block' fs/nilfs2/inode.c:73: warning: Function parameter or member 'create' not described in 'nilfs_get_block' fs/nilfs2/inode.c:145: warning: Function parameter or member 'file' not described in 'nilfs_readpage' fs/nilfs2/inode.c:145: warning: Function parameter or member 'page' not described in 'nilfs_readpage' fs/nilfs2/inode.c:968: warning: Function parameter or member 'flags' not described in 'nilfs_dirty_inode' Link: https://lkml.kernel.org/r/20220324024215.63479-1-yang.lee@linux.alibaba.com Link: https://lkml.kernel.org/r/1652276316-7791-1-git-send-email-konishi.ryusuke@gmail.com Reported-by: Abaci Robot Signed-off-by: Yang Li Signed-off-by: Ryusuke Konishi Signed-off-by: Andrew Morton Signed-off-by: Matthew Wilcox (Oracle)

nilfs2: Remove comment about releasepage

fs: Convert mpage_readpage to mpage_read_folio

2022-05-09T20:21:44Z

mpage_readpage still works in terms of pages, and has not been audited for correctness with large folios, so include an assertion that the filesystem is not passing it large folios. Convert all the filesystems to call mpage_read_folio() instead of mpage_readpage(). Signed-off-by: Matthew Wilcox (Oracle)

block: decouple REQ_OP_SECURE_ERASE from REQ_OP_DISCARD

2022-04-18T01:49:59Z

Secure erase is a very different operation from discard in that it is a data integrity operation vs hint. Fully split the limits and helper infrastructure to make the separation more clear.

block: remove QUEUE_FLAG_DISCARD

2022-04-18T01:49:59Z

Just use a non-zero max_discard_sectors as an indicator for discard support, similar to what is done for write zeroes. The only places where needs special attention is the RAID5 driver, which must clear discard support for security reasons by default, even if the default stacking rules would allow for it.
