| * | block: set S_IFBLK for block devices instead of S_IFCHR | Ahmad Fatoum | 2022-06-10 | 1 | -0/+1 |
| | | | | | | | | | | | | | | | | | | | In barebox, block devices are a special case of character devices. Nevertheless, differentiation can be useful to allow scripts iterating over all block devices without accounting for naming, e.g. for dev in /dev/*; do test -b $dev && echo $dev: blockdevice done Add the necessary support. This will break scripts that assume test -c blockdevice to be true, but that's a quite improbable check.

| * | fs: dentry cache implementation | Sascha Hauer | 2018-07-11 | 1 | -0/+315 |
| This adds the Linux dentry cache implementation to barebox. Until now every filesystem driver resolves the full path to a file for itself. This leads to code duplication and is error prone since resolving paths is a complicated task. Also it can narrow down the lookup performance since barebox only knows ASCII paths and has no way of caching lookups. With this patch we get the Linux dcache implementation. The path resolving code from fs/namei.c is nearly taken as-is, minus the RCU and locking code. Dcaching is made simple as of now: We simply cache everything and never release any dentries. Although we do reference counting for inodes and dentries it is effectively not used yet. We never free anything until a fs is unmounted in which case we free everything no matter if references are taken or not. This patch also contains a wrapper in fs/legacy.c to support filesystems with the old API. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> | |||||
