* fanotify: create FAN_ACCESS event for readdirHeinrich Schuchardt2014-06-04
| | | | | | | | | | | | | | | Before the patch, read creates FAN_ACCESS_PERM and FAN_ACCESS events, readdir creates only FAN_ACCESS_PERM events. This is inconsistent. After the patch, readdir creates FAN_ACCESS_PERM and FAN_ACCESS events.

* [readdir] introduce ->iterate(), ctx->pos, dir_emit()Al Viro2013-06-29
| | | | | | | | | | | | | New method - ->iterate(file, ctx). That's the replacement for ->readdir(); it takes callback from ctx->actor, uses ctx->pos instead of file->f_pos and calls dir_emit(ctx, ...) instead of filldir(data, ...). It does *not* update file->f_pos (or look at it, for that matter); iterate_dir() does the update. Note that dir_emit() takes the offset from ctx->pos (and eventually filldir_t will lose that argument). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* [readdir] introduce iterate_dir() and dir_contextAl Viro2013-06-29
| | | | | | | | | | | iterate_dir(): new helper, replacing vfs_readdir(). struct dir_context: contains the readdir callback (and will get more stuff in it), embedded into whatever data that callback wants to deal with; eventually, we'll be passing it to ->readdir() replacement instead of (data,filldir) pair.

* fs: reduce the use of module.h wherever possiblePaul Gortmaker2012-02-28
| | | | | | | | | | For files only using THIS_MODULE and/or EXPORT_SYMBOL, map them onto including export.h -- or if the file isn't even using those, then just delete the include. Fix up any implicit include dependencies that were being masked by module.h along the way. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* vfs: fix warning: 'dirent' is used uninitialized in this functionKevin Winchester2010-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Using: gcc (GCC) 4.5.0 20100610 (prerelease) The following warnings appear: fs/readdir.c: In function `filldir64': fs/readdir.c:240:15: warning: `dirent' is used uninitialized in this function fs/readdir.c: In function `filldir': fs/readdir.c:155:15: warning: `dirent' is used uninitialized in this function fs/compat.c: In function `compat_filldir64': fs/compat.c:1071:11: warning: `dirent' is used uninitialized in this function fs/compat.c: In function `compat_filldir': fs/compat.c:984:15: warning: `dirent' is used uninitialized in this function The warnings are related to the use of the NAME_OFFSET() macro. Luckily, it appears as though the standard offsetof() macro is what is being implemented by NAME_OFFSET(), thus we can fix the warning and use a more standard code construct at the same time.

* [PATCH] VFS: change struct file to use struct pathJosef "Jeff" Sipek2006-12-08
| | | | | | | | | | | | | This patch changes struct file to use struct path instead of having independent pointers to struct dentry and struct vfsmount, and converts all users of f_{dentry,vfsmnt} in fs/ to use f_path.{dentry,mnt}. Additionally, it adds two #define's to make the transition easier for users of the f_dentry and f_vfsmnt.

* [PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbersDavid Howells2006-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These patches make the kernel pass 64-bit inode numbers internally when communicating to userspace, even on a 32-bit system. They are required because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS for example. The 64-bit inode numbers are then propagated to userspace automatically where the arch supports it. Problems have been seen with userspace (eg: ld.so) using the 64-bit inode number returned by stat64() or getdents64() to differentiate files, and failing because the 64-bit inode number space was compressed to 32-bits, and so overlaps occur. This patch: Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit inode number so that 64-bit inode numbers can be passed back to userspace. The stat functions then returns the full 64-bit inode number where available and where possible. If it is not possible to represent the inode number supplied by the filesystem in the field provided by userspace, then error EOVERFLOW will be issued. Similarly, the getdents/readdir functions now pass the full 64-bit inode number to userspace where possible, returning EOVERFLOW instead when a directory entry is encountered that can't be properly represented. Note that this means that some inodes will not be stat'able on a 32-bit system with old libraries where they were before - but it does mean that there will be no ambiguity over what a 32-bit inode number refers to. Note similarly that directory scans may be cut short with an error on a 32-bit system with old libraries where the scan would work before for the same reasons. It is judged unlikely that this situation will occur because modern glibc uses 64-bit capable versions of stat and getdents class functions exclusively, and that older systems are unlikely to encounter unrepresentable inode numbers anyway.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
