fs: Give dentry to inode_change_ok() instead of inode

2017-02-23T03:53:52Z

commit 31051c85b5e2aaaf6315f74c72a732673632a905 upstream. inode_change_ok() will be resposible for clearing capabilities and IMA extended attributes and as such will need dentry. Give it as an argument to inode_change_ok() instead of an inode. Also rename inode_change_ok() to setattr_prepare() to better relect that it does also some modifications in addition to checks. Reviewed-by: Christoph Hellwig Signed-off-by: Jan Kara [bwh: Backported to 3.16: - Drop changes to orangefs, overlayfs - Adjust filenames, context - In nfsd, pass dentry to nfsd_sanitize_attrs() - Update ext3 as well] Signed-off-by: Ben Hutchings

Revert "fs: Give dentry to inode_change_ok() instead of inode"

2017-02-23T03:53:52Z

This reverts commit be9df699432235753c3824b0f5a27d46de7fdc9e, which was commit 31051c85b5e2aaaf6315f74c72a732673632a905 upstream. The backport breaks fuse and makes a mess of xfs, which can be improved by picking further upstream commits as I should have done in the first place. Signed-off-by: Ben Hutchings

fatfs: add FAT_IOCTL_GET_VOLUME_ID

2013-07-09T17:33:25Z

This patch, originally from Android kernel, adds vfat ioctl command FAT_IOCTL_GET_VOLUME_ID, with this command we can get the vfat volume ID using following code: ioctl(fd, FAT_IOCTL_GET_VOLUME_ID, &volume_ID) This patch is a modified version of the patch by Mike Lockwood, with changes from Dmitry Pervushin, who noticed the original patch makes some volume IDs abiguous with error returns: for example, if volume id is 0xFFFFFDAD, that matches -ENOIOCTLCMD, we get "FFFFFFFF" from the user space. So add a parameter to ioctl to get the correct volume ID. Android uses vfat volume ID to identify different sd card, when a new sd card is inserted to device, android can scan the media on it and pop up new contents.

fat: restructure export_operations

2013-04-30T01:28:40Z

Define two nfs export_operation structures,one for 'stale_rw' mounts and the other for 'nostale_ro'. The latter uses i_pos as a basis for encoding and decoding file handles. Also, assign i_pos to kstat->ino. The logic for rebuilding the inode is added in the subsequent patches.

fat: Push mnt_want_write() outside of i_mutex

2012-07-30T21:02:50Z

When mnt_want_write() starts to handle freezing it will get a full lock semantics requiring proper lock ordering. So push mnt_want_write() call outside of i_mutex as in other places. CC: OGAWA Hirofumi Signed-off-by: Jan Kara Signed-off-by: Al Viro
