* PR 9871 (partial) fix. Removed some embedded-C in ioblock.stp/vfs.stp.David Smith2010-03-301-15/+1
| | | | | | | | | * tapset/dev.stp: Added a bdevname() script function. * tapset/ioblock.stp: Rewrote the embedded-C devname function to just use bdevname() script function. * tapset/vfs.stp: Removed embedded-C __bdevname() C function. Calls bdevname() script function instead. * tapset/string.stp: Added isdigit() function.
* PR 11338 (partial): Used '@defined()' in tty, scheduler, and vfs tapsets.David Smith2010-03-081-45/+21
| | | | | | | | | | * tapset/tty.stp: Used '@defined()' to remove kernel version checks. * tapset/scheduler.stp: Ditto. * tapset/vfs.stp: Used '@defined()' to remove kernel version checks. Also made several probe points optional instead of using kernel version checks to know when to include them. * testsuite/buildok/vfs_testcase.stp: Removed stap '-u' (unoptimized mode) switch, since '@defined()' doesn't work in unoptimized mode.
* Merge sequential casts in the vfs tapsetJosh Stone2009-03-101-35/+19
| | | | | | | | | A few places in this tapset were using a pattern like this: i_sb = @cast(foo, "inode")->i_sb return @cast(foo, "super_block")->bar The type of i_sb is already known, so I just merged this to: return @cast(foo, "inode")->i_sb->bar

* This commit makes changes to the VFS tapset. The changes include deprecation ofroot2008-06-271-6/+297
| | | | | | | some old probe points to older versions of kernel, adding new helper C functions and probe points for the VFS subsystem. A new testcase is created for the VFS tapset which performs a compile test (i.e. up4) on the probe points to verify sanity. These details can also be found in the ChangeLog.

* Specified explicit types for __find_bdevname() parameters and return value. ↵mmason2007-09-261-12/+22
| | | | | | | | The types could not be determined correctly when __find_bdevname() was used in nfs.stp Added __page_index() to work around problem dereferencing unions in stap language. Made generic.fop.sendfile conditional on kernel <= 2.6.22. generic_file_sendfile() was removed in 2.6.23.
