[PATCH] common/rc: Check more options for filefrag command

[Date Prev] [Date Next] [Thread Prev] [Thread Next] [Date Index] [Thread Index]



In generic/519, filefrag command use FIBMAP ioctl(-B option) to print
output in extent format(-e option) on purpose and sync file(-s option),
so check if the command supports all of these options by _require_filefrag_options().

Rename _require_fibmap() to _require_filefrag_options()
Also remove duplicate _require_command "$FILEFRAG_PROG" filefrag

References:
1) filefrag supports -e option by commit 2508eaa since v1.42.7.
2) filefrag supports -B option by commit 5d5e01d since v1.41.9.
3) filefrag supports -s option by commit e62847c since v1.41.6.
