Add the macro CFS_FAULT_CHECK() which behaves like CFS_FAIL_CHECK() except that any site may be matched by setting CFS_FAULT (0x02000000) in cfs_fail_loc. Add cfs_fail_err for use as a return value with CFS_FAULT_CHECK(). Signed-off-by:

On some customers' systems, the kernel was compiled with HZ defined to 100, instead of 1000. This improves performance for HPC applications. However, to use these systems with Lustre, customers have to re-build Lustre for the kernel because Lustre directly uses the defined constant HZ. Since kernel 2.6.21, some non-HZ dependent timing APIs become non- inline functions, which can be used in Lustre codes to replace the direct HZ access. These kernel APIs include: jiffies_to_msecs() jiffies_to_usecs() jiffies_to_timespec() msecs_to_jiffies() usecs_to_jiffies() timespec_to_jiffies() And here are some samples of the replacement: HZ -> msecs_to_jiffies(MSEC_PER_SEC) n * HZ -> msecs_to_jiffies(n * MSEC_PER_SEC) HZ / n -> msecs_to_jiffies(MSEC_PER_SEC / n) n / HZ -> jiffies_to_msecs(n) / MSEC_PER_SEC n / HZ * 1000 -> jiffies_to_msecs(n) This patch replaces the direct HZ access in the libcfs module.

Commit b8ff756bc351 ("staging: lustre: libcfs: merge code from libcfs_ioctl into libcfs_ioctl_getdata") introduced a problem copying just a single pointer worth of data from userspace instead of whole libcfs_ioctl_hdr structure.

Change cfs_crypto_hash_final() to always clean up the hash descrptor instead of not doing this in error cases. All of the callers were just calling cfs_crypto_hash_final() immediately to clean up the descriptor anyway, and the old behaviour is unlike other init/fini functions, and prone to memory leaks and other incorrect usage. The callers can call cfs_crypto_digest_size() to determine the hash size in advance if needed, and avoid complexity in cfs_crypto_hash_final(). Signed-off-by:

This function calls some helper functions to convert the counter variant specific clock select bits into the generic enum ni_gpct_clock_source_bits equivelent. These helper functions currently BUG() if the clock select bits are invalid. It then calls ni_tio_clock_period_ps() to figure out the clock period based on the generic clock source. This function could also BUG() if the prescale bits are invalid. In reality this should never happen but refactor the code to return -EINVAL instead and remove the BUG() checks. These functions are also called by ni_tio_set_sync_mode(). When this function is called by ni_tio_set_clock_src() the counter select bits have already been validated. Signed-off-by:
