* treewide: rename leftover device_dAhmad Fatoum2023-02-211-1/+1
| | | | | | | | | We have some instances of device_d and driver_d still lingering in documentation and commented out code. Let's drop these as well.

* Rename struct device_d to deviceSascha Hauer2023-01-101-3/+3
| | | | | | | | | | | | | The '_d' suffix was originally introduced in case we want to import Linux struct device as a separate struct into barebox. Over time it became clear that this won't happen, instead barebox struct device_d is basically the same as Linux struct device. Rename the struct name accordingly to make porting Linux code easier.

* fs: Add destroy_inode callbacks to filesystemsSascha Hauer2020-07-051-0/+10
| | | | | | | | | | | Several filesystems rely on the default function which frees the struct inode * rather than the filesystem specific inode which the inode is embedded in. This works because the inode is the first element in the filesystem specific inode. Let's not depend on this behaviour and for clarity add the destroy_inode callbacks to all filesystems.

* | fs: Drop trivial .lseek() implementaitons in FS driversAndrey Smirnov2019-01-291-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are no FS drivers that do not implement .lseek callback in the codebase, so there doesn't seem to exist a use-case where lseek() would return -ENOSYS due to fsdrv->lseek being NULL. At the same time a large number of FS drivers implement only the most basic "always succeeds" custom .lseek() hook. Change the code of lseek() to treat absense of .lseek() to mean that no special actions needs to be taken by FS driver and seek is always successful and drop all of the trivial .lseek() implementations.

* | fs: Update FILE position in lseek()Andrey Smirnov2019-01-291-2/+1
|/ | | | | | | | | | Instead on relying on driver callbacks to update 'pos' in FILE, do it as a part of lseek() code. This allows us to drop a bit of repeating code as well as making lseek() implementation consistent with write() and read().

* fs: cleanup backingstore handlingSascha Hauer2013-09-291-7/+11
| | | | | | | | | | | All filesystem drivers which need a backingstore device do the same ignoring of '/dev/' in the backingstore followed by a cdev_open. Add a helper function for it and let the core handle the cdev. As a side effect this makes sure that fsdev->cdev is also set when a device is mounted without the leading '/dev/' which was previously ignored by the mount code.

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-011-7/+9
| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
