72# Above EPATCH_* variables can be used to control various defaults,

86#
87# This ensures that there are a set order, and you can have ARCH
88# specific patches.

90# If you however give an argument to epatch(), it will treat it as a
91# single patch that need to be applied if its a file. If on the other
92# hand its a directory, it will set EPATCH_SOURCE to this.

1027# basically look for the first lseek command (we do the strings/grep because
1028# sometimes the function call is _llseek or something) and steal the 2nd
1029# parameter. here is an example:
1030# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1031# lseek
1032# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
