* init: add an init_dup helperChristoph Hellwig2020-08-041-0/+12
| | | | | | | | Add a simple helper to grab a reference to a file and install it at the next available fd, and switch the early init code over to it. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* init: add an init_utimes helperChristoph Hellwig2020-07-311-0/+13
| | | | | | | Add a simple helper to set timestamps with a kernel space file name and switch the early init code over to it. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_stat helperChristoph Hellwig2020-07-311-0/+15
| | | | | | | Add a simple helper to stat with a kernel space file name and switch the early init code over to it. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_mknod helperChristoph Hellwig2020-07-311-0/+25
| | | | | | | Add a simple helper to mknod with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_mknod. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_mkdir helperChristoph Hellwig2020-07-311-0/+18
| | | | | | | Add a simple helper to mkdir with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_mkdir. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_symlink helperChristoph Hellwig2020-07-311-0/+16
| | | | | | | Add a simple helper to symlink with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_symlink. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_link helperChristoph Hellwig2020-07-311-0/+33
| | | | | | | Add a simple helper to link with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_link. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_eaccess helperChristoph Hellwig2020-07-311-0/+13
| | | | | | | | | Add a simple helper to check if a file exists based on kernel space file name and switch the early init code over to it. Note that this theoretically changes behavior as it always is based on the effective permissions. But during early init that doesn't make a difference. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_chmod helperChristoph Hellwig2020-07-311-0/+13
| | | | | | | Add a simple helper to chmod with a kernel space file name and switch the early init code over to it. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_chown helperChristoph Hellwig2020-07-311-0/+18
| | | | | | | Add a simple helper to chown with a kernel space file name and switch the early init code over to it. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_chroot helperChristoph Hellwig2020-07-311-0/+24
| | | | | | | Add a simple helper to chroot with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_chroot. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_chdir helperChristoph Hellwig2020-07-311-0/+16
| | | | | | | Add a simple helper to chdir with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_chdir. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_rmdir helperChristoph Hellwig2020-07-311-0/+5
| | | | | | | Add a simple helper to rmdir with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_rmdir. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_unlink helperChristoph Hellwig2020-07-311-0/+5
| | | | | | | Add a simple helper to unlink with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_unlink. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_umount helperChristoph Hellwig2020-07-311-0/+14
| | | | | | | | Like ksys_umount, but takes a kernel pointer for the destination path. Switch over the umount in the init code, which just happen to work due to the implicit set_fs(KERNEL_DS) during early init right now. Signed-off-by: Christoph Hellwig <hch@lst.de>
* init: add an init_mount helperChristoph Hellwig2020-07-311-0/+25
Like do_mount, but takes a kernel pointer for the destination path. Switch over the mounts in the init code and devtmpfs to it, which just happen to work due to the implicit set_fs(KERNEL_DS) during early init right now. Signed-off-by: Christoph Hellwig <hch@lst.de>
