* debugfs: provide debugfs_create_x64() when disabledJohannes Berg2013-08-271-0/+7
| | | | | | | | | | | commit 15b0beaa332b3923cc ("Add x64 support to debugfs") added debugfs_create_x64(), but forgot to provide it when debugfs is disabled, causing problems when code tries to use it even then.

|/ | | | | | | | | | | | | Some debugfs file I deal with are mostly blocks of registers, i.e. lines of the form "<name> = 0x<value>".

* debugfs: function to know if debugfs is initializedFrederic Weisbecker2009-03-231-0/+8
| | | | | | | | | | | | | | | | | Impact: add new debugfs API With ftrace, some tracers are registered in early initcalls and attempt to create files on the debugfs filesystem. Depending on when they are activated, they can try to create their file at any time. Some checks can be done on the tracing area but providing a helper to know if debugfs is registered make it really more easy.

* debugfs: add helpers for exporting a size_t simple valueInaky Perez-Gonzalez2009-01-071-0/+2
| | | | | | | | | | | | | | | | | | In the same spirit as debugfs_create_*(), introduce helpers for exporting size_t values over debugfs. The only trick done is that the format verifier is kept at %llu instead of %zu; otherwise type warnings would pop up: format ‘%zu’ expects type ‘size_t’, but argument 2 has type ‘long long unsigned int’ There is no real way to fix this one--however, we can consider %llu and %zu to be compatible if we consider that we are using the same for validating in debugfs_create_{x,u}{8,16,32}().

* debugfs: Implement debugfs_remove_recursive()Haavard Skinnemoen2008-07-211-0/+4
| | | | | | | | | | | | | | | | | | | | | debugfs_remove_recursive() will remove a dentry and all its children. Drivers can use this to zap their whole debugfs tree so that they don't need to keep track of every single debugfs dentry they created. It may fail to remove the whole tree in certain cases: sh-3.2# rmmod atmel-mci < /sys/kernel/debug/mmc0/ios/clock mmc0: card b368 removed atmel_mci atmel_mci.0: Lost dma0chan1, falling back to PIO sh-3.2# ls /sys/kernel/debug/mmc0/ ios But I'm not sure if that case can be handled in any sane manner.

* [PATCH] debugfs: Reduce <linux/debugfs.h> dependenciesRoland Dreier2005-04-181-0/+7
| | | | | | | | | | | | | | | | | | | The current <linux/debugfs.h> include file is a little fragile in that it is not self-contained and hence may cause compile warnings or errors depending on the files included before it, the kernel config and the architecture. This patch makes things a little more robust by: - including <linux/types.h> to get definitions of u32, mode_t, and so on. - forward declaring struct file_operations. - including <linux/err.h> when CONFIG_DEBUG_FS is not set The last change is particularly useful, as a kernel developer is likely to build with debugfs always enabled and never see the build breakage cased if debugfs is disabled.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+92
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!
