fs: Replace current_fs_time() with current_time()

2016-09-28T01:06:22Z

current_fs_time() uses struct super_block* as an argument. As per Linus's suggestion, this is changed to take struct inode* as a parameter instead. This is because the function is primarily meant for vfs inode timestamps. Also the function was renamed as per Arnd's suggestion. Change all calls to current_fs_time() to use the new current_time() function instead. current_fs_time() will be deleted. Signed-off-by: Deepa Dinamani Signed-off-by: Al Viro

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

configfs: move d_rehash() into configfs_create() for regular files

configfs: Replace CURRENT_TIME by current_fs_time()

2016-02-26T09:42:35Z

CURRENT_TIME macro is not appropriate for filesystems as it doesn't use the right granularity for filesystem timestamps. Use current_fs_time() instead. Signed-off-by: Deepa Dinamani Acked-by: Joel Becker Signed-off-by: Christoph Hellwig

wrappers for ->i_mutex access

2016-01-22T23:04:28Z

parallel to mutex_{lock,unlock,trylock,is_locked,lock_nested}, inode_foo(inode) being mutex_foo(&inode->i_mutex). Please, use those for access to ->i_mutex; over the coming cycle ->i_mutex will become rwsem, with ->lookup() done with it held only shared. Signed-off-by: Al Viro

configfs: implement binary attributes

2016-01-04T11:31:46Z

ConfigFS lacked binary attributes up until now. This patch introduces support for binary attributes in a somewhat similar manner of sysfs binary attributes albeit with changes that fit the configfs usage model. Problems that configfs binary attributes fix are everything that requires a binary blob as part of the configuration of a resource, such as bitstream loading for FPGAs, DTBs for dynamically created devices etc. Look at Documentation/filesystems/configfs/configfs.txt for internals and howto use them. This patch is against linux-next as of today that contains Christoph's configfs rework.

configfs: Fix potential NULL d_inode dereference

2015-02-20T09:56:43Z

Code that does this: if (!(d_unhashed(dentry) && dentry->d_inode)) { ... simple_unlink(parent->d_inode, dentry); } is broken because: !(d_unhashed(dentry) && dentry->d_inode) is equivalent to: !d_unhashed(dentry) || !dentry->d_inode so it is possible to get into simple_unlink() with dentry->d_inode == NULL. simple_unlink(), however, assumes dentry->d_inode cannot be NULL. I think that what was meant is this: !d_unhashed(dentry) && dentry->d_inode and that the logical-not operator or the final close-bracket was misplaced.
