VFS: Split DCACHE_FILE_TYPE into regular and special types

2015-02-22T16:38:38Z

Split DCACHE_FILE_TYPE into DCACHE_REGULAR_TYPE (dentries representing regular files) and DCACHE_SPECIAL_TYPE (representing blockdev, chardev, FIFO and socket files). d_is_reg() and d_is_special() are added to detect these subtypes and d_is_file() is left as the union of the two. This allows a number of places that use S_ISREG(dentry->d_inode->i_mode) to use d_is_reg(dentry) instead. Signed-off-by: David Howells Signed-off-by: Al Viro

VFS: Add a fallthrough flag for marking virtual dentries

2015-02-22T16:38:38Z

Add a DCACHE_FALLTHRU flag to indicate that, in a layered filesystem, this is a virtual dentry that covers another one in a lower layer that should be used instead. This may be recorded on medium if directory integration is stored there. The flag can be set with d_set_fallthru() and tested with d_is_fallthru().

VFS: Add a whiteout dentry type

2015-02-22T16:38:37Z

Add DCACHE_WHITEOUT_TYPE and provide a d_is_whiteout() accessor function. A d_is_miss() accessor is also added for ordinary cache misses and d_is_negative() is modified to indicate either an ordinary miss or an enforced miss (whiteout). Signed-off-by: David Howells Signed-off-by: Al Viro

VFS: Introduce inode-getting helpers for layered/unioned fs environments

2015-02-22T16:38:15Z

Introduce some function for getting the inode (and also the dentry) in an environment where layered/unioned filesystems are in operation. The problem is that we have places where we need *both* the union dentry and the lower source or workspace inode or dentry available, but we can only have a handle on one of them. Therefore we need to derive the handle to the other from that. The idea is to introduce an extra field in struct dentry that allows the union dentry to refer to and pin the lower dentry.

never used outside and it's too low-level for legitimate uses outside of fs/dcache.c anyway Signed-off-by: Al Viro
